Overview
The AP63200WU-7 is a synchronous step-down DC/DC converter from Diodes Incorporated, integrating high-side and low-side N-channel power MOSFETs. It operates with an input voltage range of 4.5V to 18V, delivering up to 2A output current. The device features fixed switching frequencies of 600kHz or 1.2MHz, selectable via the FREQ pin. Key electrical parameters include a quiescent current of 90µA in active mode and 2.5µA in shutdown. Output voltage adjustment is achieved through an external resistor divider, offering precise regulation.
Feature Summary
- Integrated synchronous rectification for improved efficiency
- Fixed frequency operation with selectable options
- Thermal shutdown and overcurrent protection mechanisms
Applications
- Portable electronics
- Industrial control systems
- Consumer appliances
Procurement Notes
Verify the specific suffix (e.g., -7) indicates the correct tape and reel packaging quantity as defined by Diodes Incorporated. Confirm the operating temperature range matches your application requirements. Ensure the PCB layout adheres strictly to the datasheet recommendations for thermal performance and stability. Cross-reference the ordering part number with official distributor catalogs to avoid counterfeit components.
Selection Notes
Select this component when a compact solution with integrated power switches is required. Consider the fixed switching frequency options based on inductor size constraints. Evaluate the input voltage range against your system's supply variations. Check the thermal characteristics if the ambient temperature exceeds standard commercial limits.
Part Context
This part belongs to the AP63xxx series of synchronous buck converters. It is designed for space-constrained applications requiring high efficiency. The WQFN-16 package facilitates surface-mount assembly. It competes with similar integrated power switch regulators from other manufacturers offering comparable current ratings and input ranges.
Replacement Considerations
Direct replacements must match the 2A current rating, 4.5V-18V input range, and WQFN-16 package. Verify pin compatibility and control interface similarities. Consult manufacturer substitution guides for electrically equivalent parts with identical thermal and electrical specifications.
