SCI7630M

The SCI7630M 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 basically consists of a reference voltage supply, comparator, and inductor driving transistors. Its output voltage is fixed internally.

The SCI7630M 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 series has four major variation. The SCI7631M and the SCI7638M operate by the clock signal
generated by an on-chip CR oscillation circuit. The SCI7633M operate by the clock signal generated by a crystal oscillation circuit. And another feature of the SCI7638M 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.
