SCI7630M/C Series

Switching Regulator

Step-up Switching Regulator

(1.5V 2.0, 2.2, 2.35, 2.4, 2.7, 2.8, 3.0, 3.1, 3.5, 3.7, 4.2 ,5.0V)

Low Operating Voltage (Min 0.9V)

Voltage Detecting function, Battery Back-up function (SCI7631M)

DESCRIPTION

The SCI7630M/C Series offers a variety of high-efficiency and low current dissipation switching regulators

produced by the silicon gate CMOS process.(An external inductor is used to implement the boosting function.)

Each SCI7630M/C basically consists of a reference voltage supply, comparator, and inductor driving transistors.

Its output voltage is fixed internally.

The SCI7630M/C Series operates with low current dissipation and low voltage. Its optional features include

voltage detecting function, battery back-up function, and stand-by function. It is thus suited for controlling the

power supply of portable or small size equipment that requires high operating efficiency.

The SCI7630M/C series has four major variation. The SCI7631M/C and the SCI7638M/C operate by the clock

signal generated by an on-chip CR oscillation circuit. The SCI7633M/C operate by the clock signal generated by

a crystal oscillation circuit. And another feature of the SCI7638M/C is its output voltage which has temperature

characteristics matching the properties of an LCD, making it suitable as the power supply of a product using an

LCD.
