Mini Buck Converter - Maxim Integrated
Description
MAX16956
EVALUATION KIT AVAILABLE
36V, 300mA, Mini Buck Converter with 1.
1µA IQ
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.
The device offers fixed-output voltages of 5V and 3.
3V, as well as an adjustable version.
The adjustable version allows the user to program the output voltage between 1V and 10V by using a resistor-divider.
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.
