LM2773  
Low-Ripple 1.8V/1.6V Spread-Spectrum Switched  
Capacitor Step-Down Regulator  
General Description  
Features  
The LM2773 is a switched capacitor step-down regulator that  
produces a selectable 1.8V or 1.6V output. It is capable of  
supplying loads up to 300mA. The LM2773 operates with an  
input voltage from 2.5V to 5.5V, accommodating 1-cell Li-Ion  
batteries and chargers.  
Low-Noise Spread Spectrum Operation  
1.8V/1.6V Selectable Output Voltage  
2% Output Voltage Regulation  
> 75% Efficiency in 1.8V Mode  
Very Low Output Ripple: 10mV @ 300mA  
Output Currents up to 300mA  
The LM2773 utilizes a regulated charge pump with gains of  
2/3x and 1x. It has very low ripple and noise on both the input  
and output due to its pre-regulated 1.15MHz (typ.) switching  
frequency and spread spectrum operation. When output cur-  
rents are low, the LM2773 automatically switches to a low-  
ripple PFM regulation mode to maintain high efficiency over  
the entire load range.  
2.5V to 5.5V Input Voltage Range  
Shutdown Disconnects Load from VIN  
1.15MHz Switching Frequency  
No Inductors…Small Solution Size  
Short Circuit and Thermal Protection  
0.5mm pitch, µSMD-9 (1.511 × 1.511mm × 0.6mm)  
The LM2773 is available in National’s 0.5mm pitch 9-bump  
Micro-SMD (µSMD-9).  
Applications  
Power Supply for DSP's, Memory, and Microprocessors  
Mobile Phones and Pagers  
Digital Cameras, Portable Music Players, and Other
