Ge n e ra l De s c rip t io n  
Fe a t u re s  
The MAX1692 is a low-noise, pulse-width-modulated  
(PWM), DC-DC step-down converter. It powers logic  
and transmitters in small wireless systems such as cellu-  
lar phones, communicating PDAs, and handy-terminals.  
The device features an internal synchronous rectifier for  
high efficiency; it requires no external Schottky diode.  
Excellent noise characteristics and fixed-frequency  
operation provide easy post-filtering. The MAX1692 is  
ideally suited for Li-Ion battery applications. It is also  
useful for +3V or +5V fixed input applications.  
♦ +2.7V to +5.5V Input Range  
♦ Adjustable Output from 1.25V to V  
IN  
♦ 600mA Guaranteed Output Current  
♦ 95% Efficiency  
♦ No Schottky Diode Required  
♦ 85µA Quiescent Current  
♦ 100% Duty Cycle in Dropout  
♦ 750kHz Fixed-Frequency PWM Operation  
♦ Synchronizable Switching Frequency  
♦ Accurate Reference: 1.25V (±1.2%)  
♦ Small 10-Pin µMAX Package  
The device operates in one of four modes. Forced PWM  
mode operates at a fixed frequency regardless of the  
load. Synchronizable PWM mode allows an external  
switching frequency to control and minimize harmonics.  
Idle Mode™ (PWM/PFM) extends battery life by switch-  
ing to a PFM pulse-skipping mode during light loads.  
Shutdown mode places the device in standby, reduc-  
ing quiescent supply current to under 0.1µA.
