Product details
Overview
AP2006SL-13 from Anachip Corp. is a dual-output monolithic DC/DC controller integrating a 250 kHz PWM buck controller (driving external PMOS) and a linear controller (driving external NPN or NMOS), with adjustable output voltage (1.23 V ±2.5%), thermal shutdown, current-limit protection, and SS/EN soft-start/enable function. It operates from 4.5–22 V input and delivers two regulated outputs in SOP-8 package for compact on-card power supplies.
For engineers reviewing the AP2006SL-13 datasheet, AP2006SL-13 pinout, AP2006SL-13 application, or AP2006SL-13 equivalent, key selection considerations include its dual-regulator architecture, 250 kHz fixed switching frequency, feedback voltage tolerance (±2.5%), SCP threshold (0.67 V typ), and SOP-8 thermal performance (400 mW PD).
Technical Context
The AP2006SL-13 implements a synchronous-capable PWM buck stage with internal 1.23 V reference and error amplifier for FB1 feedback, plus a separate linear regulator stage with 1.20–1.23 V FB2 reference and 30 mA pre-driver for external NPN/NMOS. Its 250 kHz oscillator enables smaller LC filters versus lower-frequency controllers.
Control logic integrates soft-start via constant-current charging of SS/EN pin to 2.4 V, standby mode activation via logic-level EN input (VIL ≤0.2 V, VIH ≥1.0 V), and short-circuit protection triggered at 0.67 V on SCP pin with latched shutdown at <100 mV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 250 kHz ±20% - enables use of smaller inductors and output capacitors than 100 kHz designs |
| FB1 Reference Voltage | 1.23 V ±2.5% - sets adjustable buck output as VOUT1 = 1.23 × (1 + R3/R4) |
| FB2 Reference Voltage | 1.20–1.23 V - sets linear output as VOUT2 = 1.25 × (1 + R1/R2) in typical circuits |
| SCP Threshold | 0.67 V typ - triggers short-circuit protection when sensed voltage exceeds this level |
| Quiescent Current | 6 mA max - defines minimum operating current draw during active regulation |
| Operating Voltage Range | 4.5–22 V - supports wide-input industrial and telecom supply rails |
| Power Dissipation (SOP-8) | 400 mW - limits thermal design margin in ambient up to +125°C |
Pinout & Package
AP2006SL-13 is housed in an SOP-8L (Small Outline Package, 8-lead) with standard 1.27 mm pitch, 5.05 mm width, and 3.90 mm body length. Thermal resistance θJA ≈ 312.5°C/W (calculated from 400 mW PD and 125°C max Tj).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 5) | Supply input | Primary power rail (4.5–22 V); powers internal bias, oscillator, and drivers |
| GND (Pin 4) | Ground reference | Analog and power ground return for all internal blocks and feedback networks |
| FB1 (Pin 1) | PWM output feedback | Senses buck output voltage; internal 1.23 V comparator sets regulation point |
| FB2 (Pin 2) | Linear output feedback | Senses linear regulator output; internal 1.20–1.23 V reference enables precise tracking |
| SCP (Pin 3) | Short-circuit protect input | Active-low fault input; 0.67 V threshold initiates latch-off on overcurrent |
| SS/EN (Pin 6) | Soft-start/Enable control | Logic-enable input (VIH ≥1.0 V); also accepts soft-start capacitor for controlled ramp-up |
| OUT1 (Pin 7) | PWM gate driver output | Drives external PMOS gate; 200 mA source / 300 mA sink capability |
| OUT2 (Pin 8) | Linear pre-driver output | 30 mA current-limited NPN/NMOS base/gate driver with saturation voltage ≤1.2 V |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent regulators | Simultaneous PWM buck (OUT1/FB1) and linear (OUT2/FB2) outputs reduce BOM count vs. discrete solutions |
| Integrated compensation | Internal error amplifiers eliminate need for external compensation components in standard configurations |
| Thermal shutdown & current limit | Protects IC and external switches under overload or ambient overtemperature (>125°C) |
| Low-power standby mode | EN pin disables both regulators, reducing IQ to ≤0.2 mA for system-level power gating |
| Pb-free SOP-8 package | RoHS-compliant lead finish with 260°C reflow profile compatibility |
Applications
| DSL Line Card Power | XDSL Modem Supply |
|---|---|
Use Scenario: Providing isolated 3.3 V and 1.8 V rails on DSL line cards with space constraints and thermal limits. IC Role / Device Role / Timing Role: Dual-output controller managing primary buck conversion and secondary linear post-regulation. Use Value: Reduces component count by eliminating separate linear LDO and PWM ICs while maintaining ±2.5% output accuracy. | Use Scenario: Generating stable low-noise 1.25 V core and 3.3 V I/O voltages in XDSL modems with variable load transients. IC Role / Device Role / Timing Role: PWM stage handles high-efficiency bulk conversion; linear stage filters ripple for noise-sensitive analog sections. Use Value: 250 kHz switching minimizes EMI and allows ceramic output caps; linear stage achieves <10 mVpp ripple without added filtering. |
| Industrial Sensor Node | Legacy Telecom Board |
Use Scenario: Powering microcontroller and analog sensor circuitry in battery-backed industrial nodes requiring long-term stability. IC Role / Device Role / Timing Role: Regulates from wide-input 12 V supply to 3.3 V MCU rail and 1.8 V sensor rail with enable-controlled sequencing. Use Value: SS/EN pin enables synchronized startup; 4.5–22 V range accommodates aging batteries and unregulated wall adapters. | Use Scenario: Retrofitting obsolete single-rail supplies on legacy telecom boards needing dual-voltage support. IC Role / Device Role / Timing Role: Replaces discrete transistor-based linear regulators and older PWM controllers with single SOP-8 IC. Use Value: Pin-compatible upgrade path for AP2006-series designs; maintains existing PCB layout and feedback resistor networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output DC/DC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2005SL-13 | Same pinout and topology but 150 kHz oscillator; higher VFB1 tolerance (±3%) | Lower switching frequency increases inductor size; less suitable for space-constrained designs | Select when lower EMI priority outweighs board area constraints |
| MP2307DN-LF-Z | Single-channel 2A synchronous buck only; no integrated linear controller or FB2 path | Requires external LDO for second rail; increases total solution size and cost | Choose only if dual-rail functionality is not required or can be implemented separately |
Compared with AP2005SL-13, AP2006SL-13 offers tighter feedback tolerance and higher frequency for smaller magnetics; versus MP2307DN-LF-Z, it eliminates the need for a second regulator IC but lacks synchronous rectification efficiency.

FAQ
Is AP2006SL-13 pin-compatible with AP2006DIP-13?
Yes - both share identical pin assignments (VCC, GND, FB1, FB2, SCP, SS/EN, OUT1, OUT2) and electrical specifications. The only difference is package type: SOP-8L versus DIP-8L. Layout adaptation is required for footprint, but schematic and feedback network design remain identical.
What is the maximum recommended output current for the linear controller (OUT2)?
The linear controller's pre-driver (OUT2) is rated for 30 mA continuous current into an external NPN base or NMOS gate. When driving a typical NPN with hFE=100, this supports up to ~3 A collector current - but actual safe output current depends on external transistor SOA, heatsinking, and VCC–VOUT2 headroom per the 1.2 V saturation voltage spec.
Can AP2006SL-13 operate with input voltage below 4.5 V?
No - the absolute minimum operating voltage is 4.5 V per datasheet Absolute Maximum Ratings. Below this, internal bias generation fails, oscillator stops, and regulation is not guaranteed. Startup may occur near 4.3 V (VUT threshold), but sustained operation requires ≥4.5 V.
Does AP2006SL-13 support synchronization to an external clock?
No - the 250 kHz oscillator is internal and fixed-frequency only. There is no SYNC pin or frequency adjustment interface. Applications requiring clock synchronization must use alternative controllers such as the MP2315 or RT7290B with dedicated sync inputs.
