Overview
The AP66300QFVBW-13 is a non-isolated DC/DC buck converter IC from Diodes Incorporated, designed for high-voltage automotive applications. It features an input voltage range of 3.8 V to 60 V and provides a fixed output voltage of 5 V with a maximum output current of 2 A. The device operates within a temperature range of -40°C to +125°C and utilizes a 16-UQFN package with exposed pad.
Feature Summary
- AEC-Q100 qualified for automotive reliability standards
- Integrated high-side and low-side power MOSFETs
- Peak current mode control with internal loop compensation
- Optimized output stage for reduced electromagnetic interference
Applications
- Automotive load point (PoL) regulation
- High-voltage DC-DC conversion systems
- Industrial power management modules
Procurement Notes
Verify the specific suffix '13' indicates tape and reel packaging configuration. Confirm RoHS compliance status through official datasheets. Ensure the component meets AEC-Q100 Grade 1 requirements for your target application environment.
Selection Notes
Select this part for designs requiring a 5 V output at up to 2 A from a wide 60 V input range. Consider the UQFN package for space-constrained layouts. Evaluate thermal performance based on the exposed pad design for adequate heat dissipation in enclosed environments.
Part Context
This component belongs to Diodes Incorporated's AP66300 series of synchronous buck converters. It shares architectural similarities with the AP66200 but offers distinct electrical characteristics tailored for specific current and voltage requirements in robust power supply designs.
Replacement Considerations
AP66300QFVBW-EVM serves as an evaluation tool for this device family. Cross-reference with AP66200 variants if different current ratings are required.
