General Description
The MAX1760 is a high-efficiency, low-noise, step-up
DC-DC converter intended for use in battery-powered
wireless applications. It maintains exceptionally low qui-
escent supply current (100μA) despite its high 1MHz
operating frequency. Small external components and a
tiny 10-pin μMAX package make this device an excel-
lent choice for small hand-held applications requiring
the longest possible battery life.
The MAX1760 uses a synchronous-rectified pulse-
width-modulation (PWM) boost topology to generate
2.5V to 5.5V outputs from a wide range of input
sources, such as 1 to 3 alkaline or NiCd/NiMH cells or a
single lithium-ion (Li+) cell. Maxim's proprietary Idle-
Mode circuitry significantly improves efficiency at
light load currents while smoothly transitioning to fixed-
frequency PWM operation at higher load currents to
maintain excellent full-load efficiency.
Low-noise, forced PWM mode is available for applica-
tions requiring constant-frequency operation at all load
currents. The MAX1760 may also be synchronized to
an external clock to protect sensitive frequency bands
in communications equipment. Analog soft-start and
adjustable current limit permit optimization of efficiency,
external component size, and output voltage ripple.
