DESCRIPTION  
FEATURES  
The LTC®1504A is a self-contained, high efficiency syn-  
chronous buck switching regulator. It includes a pair of  
on-chip 1.3power switches, enabling it to supply up to  
500mA of load current. Efficiency peaks at 92%, minimiz-  
ing heat and wasted power. The synchronous buck archi-  
tecture allows the output to source or sink current as  
required to keep the output voltage in regulation. 100%  
duty cycle operation minimizes dropout voltage.

The LTC1504A is available in adjustable and fixed 3.3V  
output versions. An adjustable current limit circuit pro-  
vides protection from overloads. The internal 1% refer-  
encecombinedwithasophisticatedvoltagefeedbackloop  
provides optimum output voltage accuracy and fast load  
transient response. The LTC1504A is specified to operate  
with input voltages between 4V and 10V. Contact the LTC  
factory for guaranteed specifications at 2.7V supply.
