The MAX1760/MAX1760H are high-efficiency, low-noise, step-up DC-DC converters intended for use in battery- powered wireless applications. They combine low quies- cent supply current (100µA) with a high 1MHz operating frequency. Small external components and tiny 10-pin TDFN and µMAX® packages make this device an excel- lent choice for small hand-held applications. The MAX1760 is activated by a logic-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 applica- tions 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.
