MAX16956AUBB/V+

The MAX16956AUBB/V+ is a 36V, 300mA, mini buck converter in 10 pin µMAX package. It 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. Voltage quality can be monitored by observing The RESET (active -low) signal. The device can operate near dropout by running at 97% duty cycle, making it ideal for automotive applications under cold-crank. Frequency is fixed at 2.1MHz which allows for small external components, reduced output ripple and minimized AM radio interference. The device offers both forced-PWM and skip modes of operation with ultra-low quiescent current of 1.1µA in skip mode. It is used in automotive body ECUs, point-of-load applications and distributed DC power systems.
