SC8058

General Description

The SC8058 is a versatile controller designed for use in Boost, SEPIC and power converter and to-pologies that needs an external low-side N-MOSFET acting as primary switch. Besides cycle-by-cycle current limiting, current mode control scheme also makes it wide bandwidth and good transient response. The current limit can be pro-grammedsimply with an external resistor.

The switching frequency can be set in any value between 100kHz and 1MHz with a resistor or any external clock source. The SC8058 can be operat-ed at high switching frequency to save the solu-tion board size. While entering shutdown mode,the SC8058 only sinks 5µA and it allows power supply sequencing. It has built-in protection cir-cuits such as thermal shutdown, under-voltage lockout, short circuit protection, and overvoltage

protection. Internal soft-start circuitry reduces the inrush current at start-up.
