Semtech Corporation SC1175
The SC1175 is a versatile 2 phase, synchronous, voltage mode PWM controller that may be used in two distinct ways. The SC1175 features a temperature compensated voltage reference, over current protection with 50% fold-back and internal level-shifted, high-side drive circuitry. First, the SC1175 is ideal for applications where point of use output power exceeds any single input power budget.DESCRIPTION
FEATURES
Alternatively, the SC1175 can be used as a dual switcher. 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
