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