概述
Description
ADP161AUJZ-R7 is Analog Devices’ ADP161 family fixed-frequency buck regulator. It’s a compact, high-efficiency DC-DC converter with an integrated high-side switch, designed for battery-powered portable electronics. The AUJZ suffix indicates an 8-pin package, and -R7 denotes tape-and-reel packaging. Features typically include enable control, soft-start, and protections such as current limit and thermal shutdown, with a switching frequency suitable for small, low-noise power designs. It targets mobile devices, wearables, sensors, and other MCU-powered systems that need a regulated supply from a battery. For exact specs—input/output voltage ranges, maximum load current, switching frequency, quiescent current, and pinout—consult the ADP161AUJZ-R7 datasheet and evaluation kits.
Features
Here are the typical features of the ADP161AUJZ-R7 (Analog Devices):
- High-efficiency step-down (buck) regulator with integrated high-side switch
- Input voltage range suitable for low-voltage rails (approximately 2.3–5.5 V)
- Output options: fixed-output or adjustable via external feedback network
- Fixed-frequency, current-mode control for stable operation
- Enable/shutdown control with soft-start
- Protection: overcurrent/short-circuit protection, thermal shutdown, UVLO
- Low quiescent current for good light-load efficiency
- Compact 8-pin package (AUJZ variant), suitable for small footprints
- Tape-and-reel packaging available (R7)
Note: for exact electrical specs (rated output current, exact input range, recommended external components, and fixed vs. adjustable options), please consult the current Analog Devices datasheet for ADP161AUJZ-R7.

Pinout
- Pin count: 8 pins
- Function: One-channel buck DC-DC switching regulator (integrated high-side switch). It regulates an external inductor to a desired output via the FB pin, with EN to enable/disable and a BYP pin for a bypass capacitor; VIN and GND supply the device (SW switch node drives the inductor; external diode/rectifier or synchronous path is used).
