MAX17231 Description
The MAX17230/MAX17231 offers dual synchronous stepdown DC-DC controllers with integrated MOSFETs and a step-up/boost controller. They operate over a 3.5V to 36V input voltage range, and down to 2V with the boost controller active. The devices can operate in dropout condition by running at 95% duty cycle.
