19-4305; Rev 0; 10/08 KIT ATION EVALU E L B A .. IL AVA Dual Quick-PWM Step-Down Controller with LowPower LDO and RTC Regulator for MAIN Supplies General Description The MAX17031 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 valley current-limit protection. bined with the output overvoltage and undervoltage 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...
