SC1175

SC1175 Low Power Dual Synchronous DC/DC Controller With Current Sharing Circuitry POWER MANAGEMENT Description Features The SC1175 is a versatile 2 phase, synchronous, voltage mode PWM controller that may be used in two distinct ways. First, the SC1175 is ideal for applications where point of use output power exceeds any single input power budget. Alternatively, the SC1175 can be used as a dual switcher. The SC1175 features a temperature compensated voltage reference, over current protection with 50% fold-back and internal level-shifted, high-side drive circuitry. ‹ 300kHz fixed frequency operation ‹ Soft Start and Enable function ‹ Power Good output provided ‹ Over current protection with 50% fold-back ‹ Phase-shifted switchers minimize ripple ‹ High efficiency operation, >90% ‹ Programmable output(s) as low as 1.25V ‹ Industrial temperature range ‹ 20 pin SOIC or TSSOP package In current sharing configuration, the SC1175 can produce a single output voltage from two sepa...
