LTC3406AB  
1.5MHz, 600mA  
Synchronous Step-Down  
Regulator in ThinSOT  
DESCRIPTION  
The LTC®3406AB is a high efficiency monolithic synchro-  
nous buck regulator using a constant frequency, current  
mode architecture. Supply current with no load is 200μA,  
dropping to <1μA in shutdown. The 2.5V to 5.5V input  
voltage range makes the LTC3406AB ideally suited for  
single Li-Ion battery-powered applications. 100% duty  
cycle provides low dropout operation, extending battery  
run time in portable systems. PWM pulse skipping mode  
operationprovidesverylowoutputripplevoltagefornoise  
sensitive applications. Refer to LTC3406A for applications  
that require Burst Mode® operation.  
FEATURES  
High Efficiency: Up to 96%  
600mA Output Current  
2.5V to 5.5V Input Voltage Range  
1.5MHz Constant Frequency Operation  
No Schottky Diode Required  
Low Dropout Operation: 100% Duty Cycle  
Low Quiescent Current: 200μA  
2% 0.6V Reference  
Shutdown Mode Draws <1μA Supply Current  
Internal Soft-Start Limits Inrush Current  
Current Mode Operation for Excellent Line and  
Load Transient Response  
Switching frequency is internally set at 1.5MHz, allowing  
the use of small surface mount inductors and capacitors.  
The internal synchronous switch increases efficiency  
and eliminates the need for an external Schottky diode.  
Low output voltages are easily supported with the 0.6V  
feedback reference voltage. The LTC3406AB is available  
in a low profile (1mm) ThinSOT package.  
Overtemperature Protected  
Low Profile (1mm) ThinSOTTM Package
