Overview
The AP62200TWU-7 is a synchronous buck converter from Diodes Incorporated, designed for high-voltage input applications. It accepts an input voltage range of 4.2V to 18V and delivers a continuous output current of 2A. The device features a fixed switching frequency of 750kHz and maintains a low quiescent current of 135μA in pulse frequency modulation mode. Output voltage is adjustable from 0.8V to 7V with a reference accuracy of ±1%. Packaged in a TSOT26-6 surface-mount case, it operates within a temperature range of -40°C to +85°C.
Feature Summary
- Proprietary gate driver design optimized for superior electromagnetic interference reduction without compromising switching times.
- Integrated protection circuitry including undervoltage lockout, cycle-by-cycle valley current limit, and thermal shutdown.
- High efficiency performance maintained even at light loads up to 5mA through pulse frequency modulation.
Applications
- 5V and 12V distributed power bus supplies
- Flat screen TV sets and monitors
- FPGA, DSP, and ASIC supplies
- White goods and small home appliances
Procurement Notes
Verify the specific suffix 'TWU-7' against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint for the TSOT26-6 package. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference ordering information directly with Diodes Incorporated official documentation to avoid discrepancies.
Selection Notes
Select this component when a compact solution is needed for step-down conversion from 12V or 24V systems. The 2A output capability suits moderate load requirements. Consider the 750kHz frequency for balancing component size and efficiency. Verify that the external inductor and capacitor selections support the specified ripple and transient response requirements for your target application.
Part Context
This part belongs to the AP62200 series of synchronous buck converters. It shares functional similarities with variants like AP62200WU-7 and AP62200Z6-7, differing primarily in packaging and reel specifications. The series targets general-purpose point-of-load regulation in consumer electronics and industrial equipment requiring efficient power management.
Replacement Considerations
AP62200WU-7 and AP62200Z6-7 are direct pin-compatible alternatives within the same family. Verify that the specific suffix matches your assembly requirements. No other cross-manufacturer substitutes are confirmed in public documentation.
