LTC1263

12V, 60mA Flash Memory

Programming Supply

DESCRIPTION

FEATURES

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

mountablecircuit. Theoutputcanbemomentarilyshorted

to ground without damaging the part.

■

Guaranteed 60mA Output

Regulated 12V

No Inductors

■

±5% Output Voltage

■

Supply Voltage Range: 4.75V to 5.5V

I_CC0.5µA Typ in Shutdown

Low Power: I_CC= 300µA

8-Pin SO Package

Same Pinout as LTC1262 and MAX662

The active high TTL compatible Shutdown pin can be

directly connected to a microprocessor. In the shutdown

mode, the supply current typically drops to 0.5µA.

APPLICATIONS

■

12V Flash Memory Programming Supplies
