Dual Quick-PWM, Step-Down Controller with Low-Power LDO, RTC Regulator
General Description
The MAX17101 is a dual Quick-PWM™ step-down power-supply (SMPS) controller with synchronous rectification, intended for main 5V/3.
3V power generation in battery-powered systems.
Low-side
MOSFET sensing provides a simple low-cost, highly efficient current sense for providing valley current-limit protection.
Combined with the output over
voltage and under
voltage protection features, this current limit ensures robust output supplies.
The 5V/3.
3V SMPS outputs can save power by operating in pulse-skipping mode or in ultrasonic mode to avoi...
