Maxim Integrated MAX20048ATGB/VY+, 1 Buck Boost Switching, Buck Boost Switching Regulators 50mA, 220 → 2.2 kHZ

The Maxim Integrated MAX20048 is a current-mode buck-boost controller. The device operates with input voltages from 4.5V to 36V while using only 55μA quiescent current at no load. Once the start-up conditions are satisfied, the device can operate over an extended input voltage range of 2V to 36V. The switching frequency is resistor programmable from 220kHz to 2.2MHz and can be synchronized to an external clock.
