19-4118; Rev 2; 2/09 KIT ATION EVALU E L B A AVAIL Dual Quick-PWM Step-Down Controller with Low-Power LDO, RTC Regulator General Description The MAX17020 is a dual Quick-PWM™ step-down power-supply (SMPS) controller with synchronous rectification, intended for main 5V/3.3V or I/O 1.5V/1.05V power generation in battery-powered systems. Lowside 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 or 1.5V/1.05V SMPS outputs can save power by operating in pulse-skipping mode or in ultrasonic mode to...
