Same Pinout as LTC1262 and MAX662

The LTC

converter. It provides the 12V

±5% output necessary to

program double byte-wide flash memories. The output

provides 60mA from input voltages as low as 4.75V

without using any inductors. Only four external capacitors

are required to complete an extremely small, surface

mountable circuit. The output can be momentarily shorted

to ground without damaging the part.

The active high TTL compatible Shutdown pin can be

directly connected to a microprocessor. In the shutdown

mode, the supply current typically drops to 0.5

µA.

The LTC1263 is available in an 8-pin SO package.
