Overview
The AP63356QZV-7 is a synchronous buck converter from Diodes Incorporated, housed in a V-DFN3020-13 package. It operates with an input voltage range of 3.8 V to 32 V and delivers up to 3.5 A output current. The adjustable output voltage spans from 800 mV to 32 V at a fixed switching frequency of 450 kHz. Key electrical specifications include a quiescent current of 600 nA during operation and 258 uA static current. The device supports a wide operating temperature range from -40°C to +150°C and includes shutdown functionality for power management.
Feature Summary
- Synchronous rectification design ensures high efficiency across load ranges
- Integrated compensation network reduces external component count
- Comprehensive protection features including UVLO, OVP, OCP, OTP, and SCP
Applications
- Industrial equipment power distribution
- Automotive infotainment systems
- High-voltage point-of-load regulation
Procurement Notes
Verify the specific suffix 'Q' indicates automotive grade qualification (AEC-Q100) and 'ZV' denotes the V-DFN3020-13 package variant. Confirm RoHS compliance status via official datasheets. Ensure ordering quantities align with standard reel packaging requirements specified by the manufacturer. Cross-reference pinout configurations against application schematics prior to implementation.
Selection Notes
Select this component for applications requiring high input voltage tolerance and compact footprint. The 450 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Evaluate thermal performance based on the 150°C junction temperature rating. Consider the 3.5 A continuous current capability against peak load demands to ensure adequate headroom and reliability under varying environmental conditions.
Part Context
This part belongs to the AP63356Q series of high-voltage synchronous buck converters. It shares architectural similarities with other members like the AP63357Q but differs in specific parameter tolerances and package options. The series is designed for robust performance in demanding environments, leveraging Diodes Incorporated's proprietary control techniques for stable regulation.
Replacement Considerations
AP63356DV-7 is a non-automotive grade alternative within the same family. AP63357QZV-7 offers similar electrical characteristics but may have slight variations in internal circuitry or testing standards. Verify pin compatibility and thermal resistance when substituting.
