LM2775  
SNVSA57 MAY 2015  
LM2775 Switched Capacitor 5-V Boost Converter  
1 Features  
3 Description  
The LM2775 is  
a regulated switched-capacitor  
1
2.7-V to 5.5-V Input Range  
Fixed 5-V Output  
doubler that produces a low-noise output voltage. The  
LM2775 can supply up to 200 mA of output current  
over a 3.1-V to 5.5-V input range, as well as up to  
125 mA of output current when the input voltage is as  
low as 2.7 V. At low output currents, the LM2775 can  
reduce its quiescent current by operating in a pulse  
frequency modulation (PFM) mode. PFM mode can  
be enabled or disabled by driving the PFM pin to high  
or low. Additionally, when the LM2775 is in shutdown,  
the user can chose to have the output voltage pulled  
to GND or left in a high impedance state by setting  
the OUTDIS pin high or low.  
200-mA Output Current  
Inductorless Solution: Only Requires 3 Small  
Ceramic Capacitors  
Shutdown Disconnects Load from VIN  
Current Limit and Thermal Protection  
2-MHz Switching Frequency  
PFM Operation During Light Load Currents (PFM  
pin tied high)  
The LM2775 has been placed in TI's 8-pin WSON, a  
package with excellent thermal properties that keeps  
the part from overheating under almost all rated  
operating conditions.
