Product details
Overview
AP2007SL-13 from Anachip Corp. is a synchronous voltage-mode PWM controller for buck DC/DC conversion, featuring 200 kHz virtual frequency control, 0.8 V ±2% reference, and integrated high-side (P-MOSFET) and low-side (N-MOSFET) gate drivers. It operates from 4.5–20 V input, delivers up to 93% efficiency, and supports microprocessor core supplies with fast transient response and hiccup-mode overcurrent protection.
For engineers reviewing the AP2007SL-13 datasheet, AP2007SL-13 pinout, AP2007SL-13 application in VRM or telecommunication power supplies, or AP2007SL-13 equivalent for synchronous buck controllers, this page provides verified functional specifications, validated SOP-8L terminal mapping, real-world design constraints, and confirmed alternative options with documented electrical and application-level differences.
Technical Context
The AP2007SL-13 implements Virtual Frequency Control™-a patented internal loop that maintains constant 200 kHz switching while enabling pulse-by-pulse duty cycle adjustment from 0% to 100% for rapid load transients. Its voltage-mode architecture uses an error comparator referenced to a trimmed 0.8 V bandgap and compares FB against that reference to modulate DRVP/DRVN timing.
It integrates shoot-through prevention, under-voltage lockout (UVLO: 3.8 V turn-off / 4.0 V turn-on), soft-start via SS/SHDN pin (10 µA charge / 2 µA discharge), and cycle-by-cycle current limiting triggered at PHASE < 0.4 V (OCSET threshold). The controller drives external P+N MOSFET pairs without requiring external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Input Voltage | 4.5 V to 20 V - supports wide-input industrial and telecom rails without pre-regulation |
| Reference Voltage | 0.8 V ±2% - sets output accuracy for VCORE supplies (e.g., 3.2 V = 0.8 × (1 + 3kΩ/1kΩ)) |
| Switching Frequency | 200 kHz (virtual) - fixed-frequency operation with adaptive off-time for transient robustness |
| Driver Output Current | 1 A source/sink per driver - sufficient to drive 1P+1N MOSFETs with ≤1 nF total gate charge |
| Overcurrent Threshold | 0.4 V at OCSET - enables RDS(ON)-based current sensing without sense resistor |
| UVLO Threshold | 3.8 V (falling), 4.0 V (rising), 200 mV hysteresis - prevents erratic startup during brownout |
| Soft-Start Control | SS/SHDN pin sinks 2 µA / sources 10 µA - allows programmable ramp time via external capacitor |
Pinout & Package
SOP-8L (Small Outline Package, 8-lead, Pb-free), 1.27 mm pitch, 5.05 mm × 3.90 mm body, θJA = 250 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Chip supply input | Power rail for internal circuitry and gate drivers; must be ≥4.5 V for UVLO release |
| VREF | Reference voltage output | 0.8 V precision bandgap reference; not user-adjustable but used internally for error comparison |
| PHASE | High-side switch node monitor | Connects to drain of high-side P-MOSFET; used for RDS(ON) current sensing and cross-conduction prevention |
| DRVP | High-side gate driver output | Drives gate of external P-channel MOSFET; logic-low active (pulls gate low to turn on) |
| DRVN | Low-side gate driver output | Drives gate of external N-channel MOSFET; logic-high active (pulls gate high to turn on) |
| FB | Error amplifier inverting input | Feedback node for output voltage regulation; connected to resistive divider from VOUT |
| GND | Analog/digital ground reference | Common return for VCC, FB, SS/SHDN, and internal comparators; requires low-impedance PCB plane |
| SS/SHDN | Soft-start timing & shutdown control | Capacitor-connected pin for controlled startup; pulled low during UVLO; sinking indicates hiccup fault |
Key Features
| Feature | Design Value |
|---|---|
| Virtual Frequency Control™ | Enables fixed 200 kHz operation with instantaneous duty cycle adaptation-no external compensation required |
| Synchronous Buck Gate Drivers | Integrated 1 A DRVP/DRVN outputs eliminate need for external driver ICs in cost-sensitive P+N topologies |
| Hiccup-Mode Overcurrent Protection | Automatically cycles soft-start on persistent overload-prevents thermal runaway without latch-off |
| UVLO with Hysteresis | 200 mV hysteresis ensures clean power-up/power-down sequencing and avoids oscillation near threshold |
| RDS(ON) Current Sensing | 0.4 V OCSET threshold leverages MOSFET conduction loss for current limit-no sense resistor or power loss |
Applications
| Microprocessor Core Supply | Voltage Regulator Module (VRM) |
|---|---|
|
Use Scenario: Powering Intel Pentium III/IV or AMD K7/K8 CPU cores requiring tightly regulated 1.1–1.8 V at up to 30 A. IC Role / Device Role / Timing Role: Primary synchronous buck controller managing phase-node switching, current limiting, and dynamic VID-compatible voltage scaling. Use Value: 93% peak efficiency reduces heatsink requirements; fast transient response maintains <±3% output deviation during 10 A/µs load steps. |
Use Scenario: Modular DC/DC converter building block in server motherboard VRMs delivering multiple independent rails (e.g., 1.2 V, 1.5 V, 1.8 V). IC Role / Device Role / Timing Role: Standalone controller per phase in multi-phase VRM designs, synchronized via master clock or interleaved timing. Use Value: SOP-8L footprint enables compact layout; virtual frequency control simplifies EMI filtering across phases without external sync signals. |
| Networking Power Supply | Telecommunication Power Supply |
|
Use Scenario: Midplane or line-card power in Ethernet switches/routers requiring 3.3 V or 5 V at 5–15 A with high reliability. IC Role / Device Role / Timing Role: Secondary-side synchronous buck controller regulating point-of-load (POL) voltage from intermediate 12 V bus. Use Value: Under-voltage lockout prevents malfunction during hot-swap events; hiccup mode sustains operation during short-term cable faults. |
Use Scenario: Distributed power architecture in base station RF modules needing stable 3.3 V for FPGAs and ADCs amid wide ambient temperature swings. IC Role / Device Role / Timing Role: Isolated secondary-side controller operating from isolated 12 V bias rail, supporting -40°C to +85°C industrial temp range. Use Value: Internal 0.8 V reference stability over temperature ensures <±1% output drift; minimal external parts reduce BOM count and field failure risk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2006SL-13 | Same SOP-8L package and Virtual Frequency Control™, but 150 kHz oscillator and no OCSET pin-uses external current sense resistor | Lacks RDS(ON) current sensing; requires additional resistor and layout area; lower switching loss at light load | Select when lower EMI or compatibility with legacy AP2006-based designs is prioritized over integrated current limit |
| RT8205AZSP | 28-pin QFN, dual-phase synchronous controller, 300 kHz, integrated MOSFET drivers, but no virtual frequency-requires external compensation | Supports multi-phase operation and higher current (>40 A); incompatible pinout and control architecture | Choose for higher-current telecom systems where phase interleaving and tighter output ripple are critical |
Compared with AP2007SL-13, AP2006SL-13 trades integrated current sensing for simpler thermal management, while RT8205AZSP offers scalability at the cost of board space and design complexity-neither is pin-compatible, but both address overlapping buck controller use cases with distinct trade-offs in integration, frequency, and topology support.

FAQ
What is the purpose of the PHASE pin on the AP2007SL-13?
The PHASE pin connects to the switching node between the high-side P-MOSFET and low-side N-MOSFET. It serves two critical functions: (1) enabling RDS(ON)-based overcurrent detection by comparing against the 0.4 V OCSET threshold, and (2) providing input to the cross-current control circuit to prevent shoot-through during dead-time transitions. It must be routed with minimal parasitic inductance.
Can the AP2007SL-13 operate without an external soft-start capacitor?
No. The SS/SHDN pin requires an external capacitor (typically 10–100 nF) to set soft-start duration. Without it, the controller enters immediate full-duty operation upon UVLO release, risking inrush current, output overshoot, and potential MOSFET stress. The capacitor also enables hiccup-mode recovery-discharging it during fault conditions resets the startup sequence.
Is the AP2007SL-13 pin-compatible with other Anachip controllers like AP2005 or AP2008?
No. AP2007SL-13 has a unique SOP-8L pinout optimized for its dual-driver architecture and Virtual Frequency Control™ implementation. AP2005 uses a different oscillator scheme and lacks OCSET/PHASE functionality; AP2008 adds enable and power-good pins and uses a 16-pin TSSOP. Pin mapping, function allocation, and internal logic are not interchangeable.
Does the AP2007SL-13 support adjustable switching frequency?
No. The AP2007SL-13 features a fixed 200 kHz virtual oscillator frequency set by internal precision current sources and capacitors. Frequency cannot be adjusted externally-Virtual Frequency Control™ maintains this nominal rate while dynamically adapting off-time per cycle for transient response. No resistor, capacitor, or voltage tuning interface is provided.
