FEATURES  
DESCRIPTION  
•
Operation to 36V Input Voltage  
The UC3874 family of synchronous step-down (Buck) regulators provides  
high efficiency power conversion from an input voltage range of 4.5 to 36  
volts. The UC3874 is tailored for battery powered applications such as  
laptop computers, consumer products, communications systems, and  
aerospace which demand high performance and long battery life. The  
synchronous regulator replaces the catch diode in the standard buck  
regulator with a low Rds(on) N-channel MOSFET switch allowing for  
significant efficiency improvements. The high side N-channel MOSFET  
switch is driven out of phase from the low side N-channel MOSFET switch  
by an on-chip bootstrap circuit which requires only a single external  
capacitor to develop the regulated gate drive. Fixed frequency, average  
current mode control provides the regulator with inherent slope  
compensation, tight regulation of the output voltage, and superior load and  
line transient response. Switching frequencies up to 300kHz are possible.

Duty Cycle Operation  
Light load efficiency is improved by a fully programmable standby mode, in  
which the quiescent current consumption of the controller is significantly re-  
duced. The reduction is achieved by disabling the MOSFET driver outputs  
and the internal oscillator when the controller has sensed that the the out-  
put load current has dropped a user programmable amount from full load.
