FEATURES  
DESCRIPTIO  
Uses Tiny Capacitors and Inductor  
The LTC®3561 is a constant-frequency, synchronous,  
step-down DC/DC converter. Intended for medium power  
applications,itoperatesfroma2.63Vto5.5Vinputvoltage  
range and has a user configurable operating frequency up  
to 4MHz, allowing the use of tiny, low cost capacitors and  
inductors 2mm or less in height. The output voltage is  
adjustable from 0.8V to 5V. Internal synchronous 0.11  
power switches with 1.4A peak current ratings provide  
high efficiency. The LTC3561’s current mode architecture  
and external compensation allow the transient response  
to be optimized over a wide range of loads and output  
capacitors.  
High Frequency Operation: Up to 4MHz  
High Switch Current: 1.4A  
Low RDS(ON) Internal Switches: 0.110  
High Efficiency: Up to 95%  
VIN: 2.63V to 5.5V  
Stable with Ceramic Capacitors  
Current Mode Operation for Excellent Line  
and Load Transient Response  
Short-Circuit Protected  
Low Dropout Operation: 100% Duty Cycle  
Low Shutdown Current: IQ 1µA  
Low Quiescent Current: 240µA  
To further maximize battery life, the P-channel MOSFET is  
turned on continuously in dropout (100% duty cycle). The  
no-load quiescent current is only 240µA. In shutdown, the  
device draws <1µA.  
Output Voltages from 0.8V to 5V  
Low Noise Pulse-Skipping Operation
