SC1417B Datasheet (Semtech) - Step-up DC/DC Converter

SC1417B, Step-up DC/DC Converter

The SC1417B is a fixed frequency, current mode step-up dc-dc converter.

It operates over a wide input supply range of 1.5V to 12V, making it suitable for battery input and TFT-LCD applications.

The 620kHz constant frequency oscillator minimizes the size of external components and allows simple filte

SC1417B Features

* a low battery detector and a 200mV reference circuit which remains active during shut down. The part consumes less than 50µA in shutdown. The low battery detect output goes low when the input battery voltage has dropped below a user programmable level. Pulse-by-pulse current limit and thermal shutdo
