LT3430/LT3430-1  
High Voltage, 3A,  
200kHz/100kHz Step-Down  
Switching Regulators  
DESCRIPTION  
The LT®3430/LT3430-1 are monolithic buck switching  
regulators that accept input voltages up to 60V. A high ef-  
ficiency 3A, 0.1Ω switch is included on the die along with  
all the necessary oscillator, control and logic circuitry. A  
currentmodearchitectureprovidesfasttransientresponse  
and excellent loop stability.  
FEATURES  
Wide Input Range: 5.5V to 60V  
3A Peak Switch Current over All Duty Cycles  
Constant Switching Frequency:  
200kHz (LT3430)  
100kHz (LT3430-1)  
0.1Ω Switch Resistance  
Current Mode  
Special design techniques and a new high voltage process  
achieve high efficiency over a wide input range. Efficiency  
is maintained over a wide output current range by using  
the output to bias the circuitry and by utilizing a supply  
boost capacitor to saturate the power switch. Patented  
circuitry* maintains peak switch current over the full duty  
cycle range. A shutdown pin reduces supply current to  
30µA and a SYNC pin can be externally synchronized with  
a logic level input from 228kHz to 700kHz for the LT3430  
or from 125kHz to 250kHz for the LT3430-1.  
Effective Supply Current: 2.5mA  
Shutdown Current: 30µA  
1.2V Feedback Reference Voltage  
Easily Synchronizable  
Cycle-by-Cycle Current Limiting  
Small, 16-Pin Thermally Enhanced TSSOP Package  
APPLICATIONS  
Industrial and Automotive Power Supplies
