_______________General Desc ription
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
2
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.
