ROHM BP5310 Datasheet
Regulator ICs
PCMCIA / flash memory power supply
BP5310
The BP5310 is a DC / DC converter for supplying power to PCMCIA flash memory. From a power supply (5V) for
PCMCIA operations, the IC supplies a voltage for programming operations (12V).
Applications
Personal computers, CD-ROM players, portable information devices, and other PCMCIA-slot equipped devices
Features
1) Designed to provide power for PCMCIA / flash
memory programming operations (output voltage =
12V ± 5%; output current = 120mA)
2) The 5V operating voltage is same as the IC memory
card operating voltage.
3) Built-in short-circuit protection circuit.
4) Compact 9-pin SIL package.
5) Surface mounting is possible because parts are concentrated on one side.
