AP64350QSP-13

Overview

The AP64350QSP-13 is a synchronous buck DC-DC converter manufactured by Diodes Incorporated. It operates with an input voltage range of 3.8 V to 40 V and delivers up to 3.5 A output current. The device provides an adjustable output voltage from 800 mV to 40 V. Key electrical parameters include a typical quiescent current of 22 uA, a fixed switching frequency of 500 kHz, and an operating temperature range from -40°C to +150°C. It features a shutdown function and is housed in an SO-EP-8 package.

Feature Summary

Synchronous rectification topology for high efficiency
Integrated loop compensation reduces external component count
Programmable soft-start and switching frequency control
Comprehensive protection including UVLO, OVP, OCP, OTP, and SCP

Applications

Automotive infotainment systems
ADAS sensor power supplies
Industrial control modules
High-voltage point-of-load conversion

Procurement Notes

Verify the specific suffix 'QSP' against the manufacturer's latest datasheet to confirm pinout compatibility and passivation material changes. Ensure the ordering quantity aligns with the standard reel size of 4000 units if full reels are required. Confirm RoHS3 compliance status for your specific region before finalizing procurement orders.

Selection Notes

Select this component when a wide input voltage range up to 40 V is required alongside high output current capability. The extended junction temperature rating supports operation in harsh environments. Consider the SO-EP-8 package for thermal performance requirements. Verify that the 500 kHz fixed frequency meets EMI constraints or select alternative models if programmable frequency is necessary.

Part Context

This part belongs to the AP6435 series of high-voltage synchronous buck converters from Diodes Incorporated. The series is designed for automotive and industrial applications requiring robust power management. The 'Q' designation typically indicates automotive-grade qualification under AEC-Q100 standards, ensuring reliability in demanding operational conditions.
