The LTC 1263 is a regulated 12V, 60mA output DC/DC 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.
