The MAX1760/MAX1760H are high-efficiency, low-noise,
step-up DC-DC converters intended for use in battery-powered
wireless applications. They combine low quiescent
supply current (100µA) with a high 1MHz operating
frequency. Small external components and tiny 10-pin
TDFN and µMAX® packages make this device an excellent
choice for small hand-held applications. The
MAX1760 is activated by a logic-low active-low ON signal while the
MAX1760H is activated by a logic-high ON input.
Both devices use a synchronous-rectified pulse-width-modulation
(PWM) boost topology to generate 2.5V to
5.5V outputs from a wide range of inputs, such as 1 to 3
alkaline or NiCd/NiMH cells or a single lithium-ion (Li+)
cell. Proprietary Idle-Mode™ circuitry significantly
improves light-load efficiency and smoothly transitions to
fixed-frequency PWM operation at higher load currents.
Low-noise, forced-PWM mode is available for applications
requiring constant-frequency operation at all load
currents. PWM operation can 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.
