800mA, Low-Noise, Step-Up DC-DC Converter  
with 500mA Linear Regulator  
General Description  
____________________________Features  
o High-Efficiency Step-Up Converter  
Up to 93% Efficiency  
The MAX1765 is a high-efficiency, low-noise, step-up  
DC-DC converter intended for use in battery-powered  
wireless applications. This device operates at a high  
1MHz fixed frequency while maintaining an exception-  
ally low quiescent supply current (200µA). Its small  
external components and tiny package make this  
device an excellent choice for small hand-held applica-  
tions that require the longest possible battery life.  
Adjustable Output from +2.5V to +5.5V  
Up to 800mA Output  
PWM Synchronous-Rectified Topology  
1MHz Operating Frequency (or Sync)  
o LDO Linear Regulator  
500mA LDO Linear Regulator  
2.85V Linear Regulator Output or Adjustable  
(1.25V to 5V)  
The MAX1765 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 one to three alkaline or NiCd/NiMH  
cells or a single lithium-ion (Li+) cell. Maxim's propri-  
etary architecture significantly improves efficiency at  
low load currents while automatically transitioning to  
fixed-frequency PWM operation at medium to high load  
currents to maintain excellent full-load efficiency.  
Forced-PWM mode is available for applications that  
require constant-frequency operation at all load cur-  
rents, and the MAX1765 may also be synchronized to  
an external clock to protect sensitive frequency bands  
in communications equipment.  
Low 125mV Dropout at 500mA  
o +0.7V to +5.5V Input Range  
o 0.1µA Logic-Controlled Shutdown  
o Adjustable Inductor Current Limit and Soft-Start  
o Thermal Shutdown  
o 1.5W, 16-Pin TSSOP-EP Package Available

PIN-PACKAGE  
16 QSOP  
The MAX1765’s low-dropout (LDO) linear regulator and  
DC-DC converter have separate shutdown control. The  
linear regulator's 250mΩ pass device maintains excel-  
lent dropout voltage at currents up to 500mA. The  
MAX1765 also features analog soft-start and current-  
limit functions to permit optimization of efficiency, exter-  
nal component size, and output voltage ripple.

Wireless Handsets  
PCS Phones  
Personal  
Communicators  
The MAX1765 comes in a 16-pin QSOP package and a  
thermally enhanced 16-pin TSSOP-EP.
