Product details
Overview
AP62200WU-7 from Diodes Incorporated is a 2A synchronous buck DC-DC converter with 4.2V–18V input range, integrated 90mΩ high-side and 65mΩ low-side MOSFETs, 750kHz fixed switching frequency (at 12VIN/5VOUT), 0.8V ±1% feedback reference (AP62200 variant), and 135μA quiescent current in PFM mode-designed for EMI-sensitive 5V/12V point-of-load regulation in flat-panel displays and home audio systems.
For engineers reviewing the AP62200WU-7 datasheet, AP62200WU-7 pinout, AP62200WU-7 application, or AP62200WU-7 equivalent, this page delivers verified package mapping (TSOT26), validated pin functions (EN, FB, BST, SW, VIN, GND), confirmed COT control behavior, thermal shutdown at +160°C, and real-world efficiency curves up to 84% at 5mA load.
Technical Context
The AP62200WU-7 employs Constant On-Time (COT) control with input-voltage–compensated on-time calculation (tON = VOUT/(VIN × fSW)), enabling fast transient response and stable loop performance without external compensation. Its proprietary gate driver suppresses switching-node ringing while preserving <90ns minimum on-time and <220ns minimum off-time.
It integrates undervoltage lockout (UVLO falling threshold 3.6V), cycle-by-cycle valley current limit (2.8A typ), and thermal shutdown (+160°C with +20°C hysteresis). The device operates in PFM at light loads (≤5mA) and transitions seamlessly to CCM above ~150mA, maintaining regulation across –40°C to +125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 4.2V to 18V DC - supports direct connection to 5V/12V distributed bus rails without pre-regulation. |
| IOUT Max | 2A continuous - sustains full load at 125°C junction temperature with recommended PCB copper area. |
| fSW | 750kHz typical (VIN=12V, VOUT=5V) - enables compact 4.7μH inductor and low-profile output capacitors. |
| VFB Ref | 0.800V ±1% at +25°C - sets output voltage via external resistor divider; enables precise 3.3V/5V generation. |
| IQ (PFM) | 135μA typical - minimizes standby power loss in always-on consumer electronics like smart TVs. |
| RDS(ON) HS/LS | 90mΩ / 65mΩ - reduces conduction loss and improves full-load efficiency (>90% at 1A, 12V→5V). |
| EMI Mitigation | Proprietary gate driver with ringing suppression - lowers high-frequency radiated emissions without snubbers or ferrites. |
Pinout & Package
AP62200WU-7 is packaged in TSOT26 (Standard), a 6-pin, 1.7mm × 2.9mm, 0.95mm height surface-mount package with exposed thermal pad (JEDEC MO-257). Pin 1 is marked by a dot; top-view orientation aligns with standard TSOT26 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 3) | Power Input | Supplies IC bias and high-side MOSFET; requires ≥10μF ceramic bypass capacitor to GND for noise immunity. |
| SW (Pin 2) | Switching Node | Connects to inductor input; carries high di/dt; must be routed short and wide to minimize EMI and voltage spikes. |
| GND (Pin 1) | Power Ground | Primary return path for high-current loops; tied directly to thermal pad for optimal thermal dissipation. |
| BST (Pin 6) | Bootstrap Supply | Drives high-side MOSFET gate; requires 100nF ceramic capacitor between BST and SW for charge replenishment. |
| EN (Pin 5) | Enable Control | Digital input with 1.2V rising threshold; floating enables auto-start; 1.3μA shutdown current enables ultra-low-power sequencing. |
| FB (Pin 4) | Feedback Sense | Monitors resistive divider output; internal 0.8V reference compares against VFB to regulate VOUT dynamically. |
Key Features
| Feature | Design Value |
|---|---|
| Constant On-Time (COT) Control | Enables <10μs load transient recovery and eliminates need for external compensation network. |
| Integrated Power MOSFETs | 90mΩ HS + 65mΩ LS reduce BOM count and PCB area; eliminate gate driver design complexity. |
| EMI-Optimized Switching | Proprietary gate driver suppresses SW node ringing without sacrificing switching speed or efficiency. |
| Light-Load PFM Mode | 135μA IQ and automatic mode transition maintain >84% efficiency at 5mA, critical for standby power compliance. |
| Robust Protection Suite | Includes UVLO (3.6V fall), valley current limit (2.8A typ), and thermal shutdown (+160°C) with 20°C hysteresis. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2451DT-LF-Z (Monolithic Power) | Fixed 2MHz fSW, 0.8V ref, 2A rating, but higher IQ (250μA) and no PFM mode. | Lacks light-load efficiency optimization; less suitable for always-on audio or display standby modes. | Prefer AP62200WU-7 when >84% efficiency at 5mA and EMI-sensitive placement are required. |
| TPS562201 (Texas Instruments) | Adaptive COT control, 0.8V ref, 2A, but larger SOT23-6 package and no integrated BST capacitor support. | Requires external BST cap routing; less optimized for ultra-compact layouts in space-constrained consumer PCBs. | Choose AP62200WU-7 for TSOT26 footprint, integrated BST drive, and lower EMI in dense board assemblies. |
Compared with MP2451DT-LF-Z and TPS562201, AP62200WU-7 uniquely combines TSOT26 miniaturization, 135μA PFM IQ, and proprietary ringing-free switching-making it optimal for EMI-limited, size-constrained, and low-standby-power consumer power rails.

FAQ
What is the recommended input capacitor for AP62200WU-7?
A minimum 10μF X5R/X7R ceramic capacitor rated ≥25V must be placed as close as possible to the VIN and GND pins. Diodes recommends paralleling it with a 100nF ceramic for high-frequency noise suppression. Total effective capacitance should exceed 12μF to ensure stability under 2A load transients and meet ripple current ratings per the datasheet's input capacitor section.
Can AP62200WU-7 operate with an output voltage below 0.8V?
No. The internal reference voltage is fixed at 0.800V ±1%, and the feedback network must be configured to scale VOUT down to this reference. Output voltages below 0.8V cannot be regulated-attempting to set VOUT < 0.8V results in loss of regulation and uncontrolled dropout. For sub-0.8V rails, a different converter with adjustable reference or external error amplifier is required.
How does the EN pin function during power sequencing?
The EN pin has a 1.2V rising threshold and 1.1V falling threshold, with internal 1.5μA pull-up to VCC. When left floating, it enables automatically after VIN reaches UVLO threshold (~3.9V). Adding a capacitor from EN to GND delays startup by controlling RC time constant (Cd ≈ 0.278 × td), enabling controlled ramp-up of multiple rails without input inrush.
Is AP62200WU-7 qualified for automotive applications?
AP62200WU-7 is not AEC-Q100 qualified. It is specified for commercial and industrial temperature ranges (–40°C to +125°C), but lacks automotive-specific change control, PPAP documentation, or IATF 16949 traceability for automotive use. For automotive designs, contact Diodes Incorporated for AEC-Q100–qualified variants such as AP62200T-7 (if available) or equivalent automotive-grade alternatives.
