8-Pin PDIP or SO-8 Package

The LTC

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 con-

nected to a microprocessor and reduces the supply cur-

rent to less than 0.5

µA. The LTC1262 offers improved

shutdown current performance and requires fewer exter-

nal components than competing solutions.

The LTC1262 is available in an 8-pin PDIP or SO-8

package.
