Overview
The AP62201WU-7 is a high-voltage buck switching regulator manufactured by Diodes Incorporated. It operates with an input voltage range of 4.2 V to 18 V and provides an adjustable output voltage from 800 mV to 7 V. The device delivers a continuous output current of 2 A with a fixed switching frequency of 740 kHz. It features a low quiescent current of 135 uA and supports operation within a temperature range of -40°C to +85°C. Packaged in a TSOT-26-6 surface-mount format, it integrates synchronous rectification for efficient power conversion.
Feature Summary
- Integrates synchronous rectification for improved efficiency
- Features constant on-time control for wide input/output ratios
- Includes comprehensive protection against overcurrent, overvoltage, and thermal events
Applications
- Industrial equipment power distribution
- Consumer electronics battery charging systems
- Embedded system voltage regulation
Procurement Notes
Verify the specific ordering suffix and package variant during procurement to ensure compatibility with design requirements. Confirm RoHS compliance status and check for any recent production change notices regarding material or assembly updates. Validate that the supplier source is authorized to guarantee component authenticity and traceability.
Selection Notes
Select this component when a compact solution is required for step-down conversion from 18 V sources. The TSOT-26 package suits space-constrained designs. Ensure external inductor and capacitor values align with the 740 kHz frequency for optimal performance. Verify that the load current does not exceed the 2 A rating under all operating conditions.
Part Context
This part belongs to the AP6220x series of high-voltage DC-DC converters from Diodes Incorporated. It shares architectural similarities with the AP62200 but offers specific electrical characteristics tailored for general-purpose applications. The series emphasizes small footprint solutions with integrated power switches.
Replacement Considerations
The AP62200Z6-7 is a related variant within the same product family. Verify pinout compatibility and electrical parameter alignment before substitution.
