LM2651  
SNVS032E FEBRUARY 2000REVISED JANUARY 2016  
LM2651 1.5 A High-Efficiency Synchronous Switching Regulator  
1 Features  
3 Description  
The LM2651 switching regulator provides high-  
efficiency power conversion over a 100:1 load range  
(1.5 A to 15 mA). This feature makes the LM2651 an  
ideal fit in battery-powered applications that demand  
long battery life in both run and standby modes.  
1
Ultrahigh Efficiency up to 97%  
High-Efficiency Over a 1.5-A to 1.5-mA Load  
Range  
4-V to 14-V Input Voltage Range  
1.8-V, 2.5-V, 3.3-V, or ADJ Output Voltage  
Synchronous rectification is used to achieve up to  
97% efficiency. At light loads, the LM2651 enters a  
low power hysteretic or sleep mode to maintain high  
efficiency. In many applications, the efficiency still  
exceeds 80% at 15-mA load. A shutdown pin is  
available to disable the LM2651 and reduce the  
supply current to less than 10 µA.  
Internal MOSFET Switch With Low RDS(on) of  
75 m  
300-kHz Fixed Frequency Internal Oscillator  
7-µA Shutdown Current  
Patented Current Sensing for Current Mode  
Control  
The LM2651 contains a patented current sensing  
circuitry for current mode control. This feature  
eliminates the external current sensing resistor  
required by other current-mode DC-DC converters.  
Input Undervoltage Lockout  
Adjustable Soft-Start  
Current Limit and Thermal Shutdown  
16-Pin TSSOP Package  
The LM2651 has a 300-kHz fixed frequency internal  
oscillator. The high oscillator frequency allows the  
use of extremely small, low-profile components.  
2 Applications  
A
programmable soft-start feature limits current  
Personal Digital Assistants (PDAs)  
Computer Peripherals  
surges from the input power supply at start-up and  
provides a simple means of sequencing multiple  
power supplies.  
Battery-Powered Devices  
Handheld Scanners  
Other protection features include input undervoltage  
lockout, current limiting, and thermal shutdown.
