Overview

The AP61100Z6-7 is a 1A, synchronous step-down converter with a wide input voltage range of 2.3V to 5.5V. It utilizes Constant On-Time (COT) control to achieve fast transient response and ease of loop stabilization, while operating at a high 2.2MHz switching frequency to minimize external component size.

Why Choose This Part

This regulator features an exceptionally low 15uA quiescent current, significantly extending battery life in standby modes. It offers flexible operation modes, allowing engineers to prioritize either high efficiency via PFM or low noise via PWM regardless of the output load.

Applications

Battery-Powered IoT Devices
Ideal for low-power wireless sensors and wearables requiring high efficiency at light loads via Pulse Frequency Modulation (PFM) mode.
Point-of-Load Regulation
Efficiently steps down 3.3V or 5V system rails to low-voltage cores (0.6V to 3.6V) for MCUs and FPGAs.
Space-Constrained Electronics
The ultra-small SOT-563 package and 2.2MHz switching frequency allow for a minimal PCB footprint and small inductors.

Getting Started

To implement the AP61100Z6-7, place the input ceramic bypass capacitor as close as possible to the VIN and GND pins to minimize EMI. Use the EN pin to toggle between PFM and PWM modes for specific application noise requirements, and refer to the datasheet for selecting the feedback resistor network for the desired output voltage between 0.6V and 3.6V.
