memory
BP5320
The BP5320 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). Compact and thin surface-mounted
package with embossing tape for automatic mounting.
Applications
Personal computers, CD-ROM players, portable information devices, and other PCMCIA-slot equipped devices
Features
1) Designed to provide power to PCMCIA programming
operations.
2) The 5V operating voltage is same as the IC memory
card operating voltage.
3) The large current enables power to be supplied to
sound ICs.
Absolute maximum ratings (Ta=25C)
4) Compact and thin SMD package.
5) Supplied with embossing tape for automatic mounting by the mounter.
6) Built-in short-circuit protection circuit.
