Overview
The AP63301WU-7 is a synchronous buck DC-DC converter from Diodes Incorporated, housed in a TSOT-26-6 package. It delivers a continuous output current of 3 A with an input voltage range of 3.8 V to 32 V and adjustable output voltages from 800 mV to 31 V. Operating at a fixed switching frequency of 500 kHz, the device integrates high-side (75 mΩ) and low-side (40 mΩ) power MOSFETs. Quiescent current is specified at 22 uA, and it functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrated proprietary gate driver scheme suppresses switch node ringing to reduce high-frequency radiated EMI noise without compromising MOSFET transition times.
- Fully integrated synchronous rectification includes high-side and low-side power MOSFETs for efficient step-down conversion.
- Optimized design minimizes electromagnetic interference through specialized control architecture.
Applications
- High-voltage buck conversion systems
- Portable equipment power management
- Industrial control power supplies
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package integrity and pin alignment prior to assembly. Ensure storage conditions comply with moisture sensitivity levels. Validate that the specific suffix matches required specifications. Cross-reference ordering information with authorized distributor catalogs to ensure correct revision status.
Selection Notes
Select this component for applications requiring wide input voltage ranges up to 32 V and high output currents. The TSOT-26-6 package offers space efficiency for dense layouts. Consider the 500 kHz switching frequency for balancing component size and efficiency. Verify thermal requirements based on load conditions and ambient temperature constraints.
Part Context
This part belongs to the AP6330x series of high-voltage synchronous buck converters. It shares architectural similarities with other members like the AP63201 but differs in output current capacity and specific integration features. The series targets compact power solutions requiring robust performance in limited spaces.
Replacement Considerations
AP63300WU-7 is a related variant within the same family. Verify compatibility regarding output current ratings and specific electrical characteristics before substitution. Consult official documentation for detailed comparison of pinouts and functional differences.
