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
