Maxim Integrated
General Description
The MAX16956 is a small, synchronous buck converter with integrated high-side and low-side switches. The device is designed to deliver up to 300mA with input voltages from 3.5V to 36V, while using only 1.1µA quiescent current at no load (fixed-output versions). Voltage quality can be monitored by observing the RESET signal. The device can operate near dropout by running at 97% duty cycle, making it ideal for automotive applications under cold-crank.
