The
μ
PD16901 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
