AP63301QWU-7

Overview

The AP63301QWU-7 is a synchronous buck DC-DC converter from Diodes Incorporated, housed in a TSOT-26-6 package. It delivers a continuous output current of 3 A with an input voltage range of 3.8 V to 32 V and an adjustable output voltage from 800 mV to 31 V. The device integrates high-side and low-side power MOSFETs, operates at a switching frequency of 500 kHz, and draws a typical quiescent current of 22 uA. It functions within an operating temperature range of -40°C to +85°C.

Feature Summary

Integrates high-side and low-side power MOSFETs for efficient step-down conversion
Features proprietary gate drive design to suppress switch node ringing and reduce EMI noise
Includes comprehensive protection mechanisms such as UVLO, OVP, OCP, OTP, and hiccup mode short-circuit protection

Applications

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

Procurement Notes

Verify the Q suffix indicates automotive qualification compliance, specifically AEC-Q100 standards. Confirm the specific tape-and-reel quantity matches project requirements. Ensure the TSOT-26-6 footprint aligns with the PCB layout. Check for moisture sensitivity level (MSL) handling instructions during assembly. Validate that the operating temperature range meets the environmental constraints of the final application.

Selection Notes

Select this component when a compact solution is required for high-current applications with wide input voltage variations. The integrated MOSFETs simplify the bill of materials by reducing external component count. The low quiescent current supports battery-powered or standby-sensitive designs. The EMI reduction features are advantageous for noise-sensitive environments without requiring extensive filtering.

Part Context

This part belongs to the AP63300/01 series of synchronous buck converters designed for robust performance in demanding environments. The series emphasizes high efficiency and electromagnetic compatibility through specialized internal circuitry. It serves as a key power management solution for systems requiring reliable voltage regulation under varying load conditions.
