Description

The SCI7631, SCI7638 series of CMOS switching regulators provide input voltage step-up and regulation  to a specified fixed voltage using an external coil.

The devices in these series incorporate precision, low-power reference voltage generators and transistors for driving an internal comparator. They feature low power con sumption, low operating voltages, voltage detection and standby operation.

Features

• 0.9V (Min.) operating voltage

• 10mA (Typ.) maximum current consumption

• Standby operation

• 3mA (Typ.) standby current consumption

• 1.05 ±0.05V high-accuracy voltage detection

• Battery backup (available on SCI7631 series)

• On-chip RC oscillator

Applications:

• Fixed-voltage power supplies for battery-operated equipment such as portable video cassette recorders, video cameras and radios

• Power supplies for pagers, memory cards, calculators and similar hand-held equipment

• Fixed-voltage power supplies for medical equipment

• Fixed-voltage power supplies for communications equipment
