FEATURES  
DESCRIPTION  
The LTC®1435A is a synchronous step-down switching  
regulator controller that drives external N-channel power  
MOSFETs using a fixed frequency architecture. A wide  
dutycyclerangeof5%to99%allowshighVIN tolowVOUT  
DC/DC conversion, as well as low dropout operation that

ModeTM operation provides high efficiency at low load  
currents.

Logic Controlled Micropower Shutdown: IQ < 25µA  
Foldback Current Limiting (Optional)  
Current Mode Operation for Excellent Line and Load  
Transient Response  
The operating frequency is set by an external capacitor  
allowing maximum flexibility in optimizing efficiency. A  
secondary winding feedback control pin, SFB, guarantees  
regulation regardless of load on the main output by  
forcing continuous operation. Burst Mode operation is  
inhibited when the SFB pin is pulled low, which reduces  
noise and RF interference.  
■
■
Output Voltages from 1.19V to 9V  
Available in 16-LUead Narrow SO and SSOP Packages  
Soft start is provided by an external capacitor that can be  
used to properly sequence supplies. The operating cur-  
rent level is user-programmable via an external current  
sense resistor. Wide input supply range allows operation  
from 3.5V to 30V (36V maximum).
