SC4608 Datasheet High Efficiency Synchronous Buck

Manufacturer: SEMTECH

Overview: Low Input, MHz Operation, High Efficiency Synchronous Buck POWER.

General Description

The SC4608 is a voltage mode step down (buck) regulator controller that provides accurate high efficiency power conversion from an input supply range of 2.7V to 5.5V.

A high level of integration reduces external ponent count, and makes it suitable for low voltage applications where cost, size and efficiency are critical.

The SC4608 is capable of producing an output voltage as low as 0.5V.

Key Features

  • Asynchronous start up Programmable switching frequency up to 1MHz BiCMOS voltage mode PWM controller 2.7V to 5.5V input voltage range Output voltage as low as 0.5V +/-1% reference accuracy Sleep mode (Icc = 1µA max) Adjustable lossless short circuit current limiting Combination pulse by pulse & hiccup mode current limit High efficiency synchronous switching 1A peak current driver External soft start Power good signal 16-pin MLP Lead-free package. This product is fully WEEE and RoHS compliant Dis.
