Synchronous Step Down Controller with 50 mA Linear Regulator

Obsolete

概览

The NCP1578 is a voltage mode synchronous step-down controller for high performance systems intended to be used in battery-powered systems. The NCP1578 includes a high efficiency PWM controller with adjustable output, and a 5V/50mA linear regulator. A pin is provided to enable or disable forced PWM mode of operation. An internal power good voltage monitor tracks the SMPS output. NCP1578 also features soft-start sequence, UVLO for linear regulator and switcher, overvoltage protection, overcurrent protection, and thermal shutdown. The IC is packaged in QFN-20
