SC195F - Semtech

SC195F 500mA Synchronous Step Down DC-DC Regulator

The SC195F is a high efficiency, 500mA step down regulator designed to operate with an input voltage range of 2.9V to 5.5 V. The input voltage range makes it ideal for battery operated applications with space limitations. The SC195F operates at a fixed 3.5MHz switching frequency in normal PWM (Pulse-Width Modulation) mode. The SC195F also includes fifteen pr.
