LTC3832/LTC3832-1  
High Power Step-Down  
Synchronous DC/DC Controllers  
for Low Voltage Operation  
U
FEATURES  
DESCRIPTIO  
The LTC®3832/LTC3832-1 are high power, high effi-  
ciency switching regulator controllers optimized for  
3.3V-5V to 0.6V-3.xV step-down applications. A preci-  
sion internal reference and feedback system provide  
±1% output regulation over temperature, load current  
andlinevoltagevariations. TheLTC3832/LTC3832-1use  
a synchronous switching architecture with N-channel  
MOSFETs. Additionally, the chip senses output current  
through the drain-source resistance of the upper  
N-channelMOSFET, providinganadjustablecurrentlimit  
without a current sense resistor.

High Power Switching Regulator Controller  
for 3.3V-5V to 0.6V-3.xV Step-Down Applications  
■
No Current Sense Resistor Required  
■
Low Input Supply Voltage Range: 3V to 8V  
■
Maximum Duty Cycle >91% Over Temperature  
■
All N-Channel External MOSFETs  
■
Excellent Output Regulation: ±1% Over Line, Load  
and Temperature Variations  
■
High Efficiency: Over 95% Possible  
■
Adjustable or Fixed 2.5V Output (LTC3832)  
■
Programmable Fixed Frequency Operation: 100kHz to  
The LTC3832/LTC3832-1 operate with an input supply  
voltage as low as 3V and with a maximum duty cycle of  
>91% over temperature. They include a fixed frequency  
PWMoscillatorforlowoutputrippleoperation.The300kHz  
free-running clock frequency can be externally adjusted or  
synchronizedwithanexternalsignalfrom100kHzto500kHz.  
In shutdown mode, the LTC3832 supply current drops to  
<10µA.TheLTC3832-1istheSO-8versionwithoutcurrent
