DESCRIPTION
The SC1409 is a versatile, voltage-mode switching
regulator designed for use in battery operated power supply applications.
A simple, fixed-voltage buck
regulator can be implemented using the SC1409 with a minimum of external components.
Internal MOSFETs and control circuitry minimize board space and design time.
The small device footprint allows for compact circuit design.
SC1409 features include a temperature compensated voltage reference, triangle wave oscillator, hiccup mode current limit, an internally compensated error amplifier, overcurrent temperature p...
