Overview

Low Input, MHz Operation, High Efficiency Synchronous Buck POWER MANAGEMENT Description The SC4609 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 component count, and makes it suitable for low voltage applications where cost, size and efficiency are critical.
The SC4609 is capable of producing an output voltage as low as 0.
5V.
SC4609 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...
