The BP5310A is a DC / DC converter for supplying power to PCMCIA flash memory. From a power supply (+5V) for PCMCIA operations, the module supplies a voltage for programming operations (+12V).

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 protection circuit for shorted-circuit.
4) Compact 9-pin SIP package.
5) Surface mounting is possible because parts are concentrated on one side.
