Product Summary

The SC4524SETRT is an adjustable frequency peak currentmode step-down switching regulator with an integrated 2.3A, 30V switch. The SC4524SETRT can be programmed up to 1.5MHz. This allows the use of small inductor and ceramic capacitors, resulting in very compact power supplies. The SC4524SETRT is suitable for next generation XDSL modems, set-top boxes and point of load applications. The SC4524SETRT uses peak current-mode PWM control for ease of compensation. Cycle-by-cycle current limit and hiccup overload protection reduce power dissipation during overload. Combined soft start and enable pin not only eliminates output start up overshoot but also allows power sequencing. The SC4524SETRT is available in SOIC-8 EDP package. Applications are (1)XDSL and cable modems; (2)Set-top boxes; (3)Point of load applications; (4)CPE equipment; (5)DSP power supplies; (6)Disk drives.
