12V, 30mA Flash Memory Programming Supply
Linear Technology Inc.

Description
The LTC?1262 is a regulated 12V, 30mA output DC/DC converter. It is designed to provide the 12V 5% output necessary to program byte-wide flash memories. The output will provide up to 30mA 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 TTL compatible shutdown pin can be directly connected to a microprocessor and reduces the supply current to less than 0.5?A. The LTC1262 offers improved shutdown current performance and requires fewer external components than competing solutions. The LTC1262 is available in an 8-pin PDIP or SO-8 package.
