AP64351QSP-13

Overview

The AP64351QSP-13 is a synchronous step-down 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 of output current. The device features a fixed switching frequency of 570 kHz and supports adjustable output voltages up to 40 V. It includes a shutdown function and maintains a low quiescent current of 22 uA. The component is housed in an SO-EP-8 package and is rated for operation between -40°C and +150°C.

Feature Summary

Synchronous buck topology for high efficiency
Integrated 570 kHz fixed switching frequency
Low quiescent current consumption
Automotive-grade reliability

Applications

Automotive infotainment systems
Telematics control units
Body electronics modules
Industrial power distribution

Procurement Notes

Verify the specific suffix QSP against official Diodes Incorporated documentation to confirm package type and automotive qualification status. Ensure compatibility with required thermal management solutions given the operating temperature range. Confirm RoHS compliance details via the latest datasheet revision before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 570 kHz frequency is required to simplify EMI filtering compared to programmable variants. The 3.5 A output capability suits moderate load applications. Verify that the 40 V maximum input voltage aligns with system bus requirements, as higher voltage inputs necessitate alternative models within the series.

Part Context

This part belongs to the AP6435x family of high-voltage synchronous buck converters from Diodes Incorporated. The family shares common control architectures but varies in switching frequency and maximum input voltage ratings. The AP64351QSP-13 specifically targets automotive applications requiring robust performance under wide temperature conditions.

Replacement Considerations

AP64352QSP-13 offers similar current handling with programmable frequency. AP64351SP-13 provides non-automotive grade alternatives. Cross-reference pinouts and thermal characteristics carefully when substituting.
