Overview

The AP61102Z6-7 is a 1A synchronous buck converter with a wide input voltage range of 2.3V to 5.5V and a high switching frequency of 2.2MHz. It features an extremely low quiescent current of 15uA and a power-good indicator, making it ideal for battery-powered systems requiring high efficiency at light loads. The device is housed in a compact SOT-563 package, minimizing the total PCB footprint for space-constrained designs.

Why Choose This Part

The 2.2MHz switching frequency allows for the use of small surface-mount inductors and capacitors, reducing overall BOM size. It offers versatile operation modes through the EN pin, supporting Pulse Frequency Modulation (PFM) for light-load efficiency or forced PWM for low output ripple. Integrated protection features including overvoltage protection, cycle-by-cycle current limit, and thermal shutdown ensure robust operation.

Applications

Battery-Powered IoT Nodes
Utilizes the 15uA low quiescent current to extend battery life in devices that spend significant time in standby modes.
Point-of-Load Regulation
Provides efficient 1A down-conversion from 5V or 3.3V rails to low-voltage cores as low as 0.6V.
Portable Medical Devices
Small SOT-563 form factor and high efficiency are suitable for handheld diagnostic and monitoring equipment.

Getting Started

To evaluate this part, design a PCB layout that places the input ceramic bypass capacitor as close as possible to the VIN and GND pins to minimize parasitic inductance. Refer to the datasheet for calculating the feedback resistor network to set the desired output voltage between 0.6V and 3.6V. Ensure the power-good pin is pulled up to a logic rail if system-level monitoring is required.
