General Doacription
The MAX732/MAX733 are CMOS step-up DG-DC switch-
mode regulators. The MAX732 is a +12V regulator that
accepts inputs from 4.0V to 9.3V and delivers up to
200mA of DC current. The MAX733 is a +15V regulator
that delivers up to 125mA and accepts inputs from 4.0V
to 11.0V. Typical full-load efficiencies are 85% to 92%.
They require only a single inductor value of sum to
function over their entire ranges, so no inductor-related
design is necessary. Accuracy is guaranteed over
temperature, line, and load variations. The MAX732/
MAX733 use a current-mode pulse-width modulation
(PWM) controller to provide precise output regulation
and low subharmonic noise. Typical no load supply
current is 1.7mA. Fixed 170kHz oscillator frequencies
allow easy filtering ot ripple and noise and provide for
small external components.
The MAX732/MAX733 feature cycle-by-cycle current
limiting, overcurrent limiting, undervoltage lockout, and
programmable soft-start protection.
For an adiustable version of these devices, refer to the
MAX752 data sheet. For lower-power step-up applica-
tions, refer to the MAX632/MAX633 and MAX642/
MAX643 data sheets. For more applications information,
