AP61302Z6-7

Overview

The AP61302Z6-7 is a low quiescent current synchronous buck converter manufactured by Diodes Incorporated. It operates with an input voltage range of 2.4 V to 5.5 V and provides a single adjustable output from 600 mV up to the input voltage. The device delivers a continuous output current of 3 A at a fixed switching frequency of 2.2 MHz. It features a shutdown function and operates within a temperature range of -40°C to +125°C. Packaged in a compact SOT-563-6 surface-mount case, it draws only 19 µA of static current.

Feature Summary

• Integrates synchronous rectification for high efficiency across load ranges
• Includes a dedicated shutdown pin for power management control
• Utilizes a compact six-pin SOT-563 package for space-constrained designs

Applications

• Portable consumer electronics requiring efficient step-down regulation
• Battery-powered devices needing extended operational life
• Embedded systems utilizing 3.7V or 5V battery sources

Procurement Notes

Verify the specific suffix Z6-7 against official Diodes Incorporated documentation to confirm the SOT-563-6 package and tape-and-reel quantity. Ensure compatibility with your PCB footprint and reflow profile requirements. Cross-reference the datasheet revision date to confirm electrical characteristics match your design specifications before finalizing procurement orders.

Selection Notes

Select this component when a 3 A output current is required from a 2.4 V to 5.5 V input source. It is suitable for applications prioritizing low standby current due to its 19 µA quiescent specification. Consider the 2.2 MHz switching frequency for balancing electromagnetic interference and external component size compared to lower-frequency alternatives.

Part Context

This part belongs to the AP61x0x series of low IQ synchronous buck converters from Diodes Incorporated. It shares the same family topology as variants like the AP61300Z6-7 but differs in maximum output current capability. The series is designed for portable applications where power efficiency and small form factor are critical constraints.

Replacement Considerations

AP61300Z6-7 is listed as a substitute variant within the same manufacturer portfolio.
