SC1409: 1 A Synchronous Switching Regulator | Semtech

The SC1409 is a versatile, voltage-mode switching Regulator designed for use in battery operated power supply applications. A simple, fixed-voltage buck regu- lator 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.
