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 con-
nected to a microprocessor and reduces the supply cur-
rent to less than 0.5
μ
A. 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.
