DC-DC Converter
General Description
The MAX1763 is a high-efficiency, low-noise, step-up
DC-DC converter intended for use in battery-powered
wireless applications. This device maintains exception-
ally low quiescent supply current (110μA) despite its
high 1MHz operating frequency. Small external compo-

? Up to 94% Efficiency
? +0.7V to +5.5V Input Voltage Range
? 1.1V Guaranteed Startup Input Voltage
? Up to 1.5A Output
nents and a tiny package make this device an excellent
choice for small hand-held applications that require the
longest possible battery life.
The MAX1763 uses a synchronous-rectified pulse-
width-modulation (PWM) boost topology to generate

sources, such as one to three alkaline or NiCd/NiMH
cells or a single Lithium-ion (Li+) cell. Maxim's propri-
etary Idle Mode? circuitry significantly improves effi-
ciency at light load currents while smoothly transitioning
to fixed-frequency PWM operation at higher load cur-
rents to maintain excellent full-load efficiency. Low-
noise, forced-PWM mode is available for applications

________________________Applications
that require constant-frequency operation at all load
currents. The MAX1763 may also be synchronized to
an external clock to protect sensitive frequency bands
in communications equipment.
The MAX1763 includes an on-chip linear gain block
that can be used to build a high-power external linear
regulator or as a low-battery comparator. Soft-start and
current limit functions permit optimization of efficiency,
external component size, and output voltage ripple.
