FLASH MEMORY VOLTAGE STEPUP DC/DC CONVERTER IC

The µPD16901 is a DC/DC converter IC which produces a 12 V output from a 5 V input source. The integration of a control circuit and power MOSFET in the output stage on a single-chip allows a power supply for flash memory write and erasure to be configured with a reduced number of external components.

FEATURES

• With an on-chip output stage power MOSFET, fewer external components are needed.

• The ALLMOS structure achieves low power consumption.

• Internally set output voltage eliminates the need for adjustment.

• Output can be turned ON/OFF via an external signal.

• A timer latch type overcurrent protection circuit on chip
