The SC4602A/B is a voltage mode step down (buck) regulator controller that provides accurate high efficiency power conversion from an input supply range of 2.75V to 5.5V. A high level of integration reduces external component count and makes it suitable for low voltage applications where cost, size and efficiency are critical. The SC4602A/B drives external c.
BICMOS Voltage mode PWM controller 2.75V to 5.5V Input voltage range Output voltages as low as 0.8V +/-1% Reference accuracy Sleep Mode (Icc = 10µA typ) Lossless short circuit current limiting Combination pulse by pulse & hiccup mode current limit High efficiency synchronous switching Up to 100% Duty cycle range Synchronization to external clock 8-Pin MSOP surface mount package. Lead-free package available, fully WEEE and RoHS compliant Applications Distributed power system RF power supply Local microprocessor core power supplies DSP and I/O power supplies Ba.
