The MAX662A is a regulated +12V, 30mA-output, charge-

pump DC-DC converter. It provides the necessary +12V

±5% output to program byte-wide flash memories, and

requires no inductors to deliver a guaranteed 30mA out-

put from inputs as low as 4.75V. It fits into less than 0.1in

of board space. The MAX662A is a pin-compatible

upgrade to the MAX662, and is recommended for new

designs. The MAX662A offers lower quiescent and shut-

down currents, and guarantees the output current over all

temperature ranges.

The MAX662A is the first charge-pump boost converter to

provide a regulated +12V output. It requires only a few

inexpensive capacitors, and the entire circuit is complete-

ly surface-mountable.

A logic-controlled shutdown pin that interfaces directly

with microprocessors reduces the supply current to only

0.5µA. The MAX662A comes in 8-pin narrow SO and DIP

packages.

For higher-current flash memory programming solutions,

refer to the data sheets for the MAX734 (120mA output

current, guaranteed) and MAX732 (200mA output cur-

rent, guaranteed) PWM, switch-mode DC-DC converters.

Or, refer to the MAX761 data sheet for a 150mA, PFM

switch-mode DC-DC converter that operates from inputs

as low as 2V.
