SC1409 General 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 protection, soft start, and under voltage lock out.
The SC1409 operates at a selectable, fixed frequency of 300kHz or 500kHz, or can be synchronized to an external clock within this range, providing an optimum compromise between efficiency, external component size, and cost.
