AP61102Z6-7

Overview

The AP61102Z6-7 is a low quiescent current synchronous buck converter manufactured by Diodes Incorporated. It operates with an input voltage range of 2.3 V to 5.5 V and delivers up to 1 A output current. The adjustable output voltage spans from 600 mV to 3.6 V. Integrated features include a fixed 2.2 MHz switching frequency and a shutdown mode with 15 uA static current. The device functions within an operating temperature range of -40°C to +85°C and is housed in a compact SOT-563-6 surface-mount package.

Feature Summary

• Synchronous rectification architecture for improved efficiency
• Integrated power switch and control logic
• Fixed high-frequency operation to minimize external component size
• Thermal protection and over-current limiting capabilities

Applications

• Portable consumer electronics power management
• Battery-powered handheld devices
• Embedded systems requiring efficient step-down conversion
• IoT sensor nodes and low-power applications

Procurement Notes

Verify the specific ordering suffix Z6-7 corresponds to the standard tape-and-reel packaging configuration as documented in the official Diodes Incorporated datasheet. Confirm that the SOT-563-6 package dimensions align with the target PCB footprint requirements. Ensure compliance with RoHS directives and check for any regional distribution restrictions or supply chain limitations prior to finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring a single-output low-voltage buck converter with moderate current capacity. The 2.2 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 15 uA quiescent current for battery life optimization. Verify that the maximum input voltage of 5.5 V accommodates the highest source voltage without exceeding absolute maximum ratings during transient conditions.

Part Context

This part belongs to the AP61102 series of low IQ synchronous buck converters from Diodes Incorporated. It shares architectural similarities with other members like the AP61100QZ6 but differs in specific electrical parameters such as output current capability and fixed switching frequency. The series targets applications needing efficient power regulation in space-constrained environments, utilizing the same SOT-563-6 package form factor for design compatibility across related product lines.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's official cross-reference guides or contact Diodes Incorporated directly for validated equivalent components that match the electrical specifications and pinout configuration.
