19-1660; Rev 1; 1/01  
0.8A, Low-Noise, 1MHz,  
Step-Up DC-DC Converter  
General Description  
Features  
ꢀ Up to 94% Efficiency  
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.  
ꢀ 0.7V to 5.5V Input Range  
ꢀ Up to 800mA Output  
ꢀ Fixed 3.3V Output (or adj from 2.5V to 5.5V)  
ꢀ PWM Synchronous Rectified Topology  
ꢀ Low-Noise, Constant Frequency Operation (1MHz)  
ꢀ 0.1µA Logic-Controlled Shutdown  
ꢀ Synchronizable Switching Frequency  
ꢀ Adjustable Current Limit  
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.  
ꢀ Adjustable Soft-Start  
ꢀ 10-Pin µMAX Package  
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.
