LM4510  
Synchronous Step-Up DC/DC Converter with True  
Shutdown Isolation  
General Description  
The LM4510 is a current mode step-up DC/DC converter with  
a 1.2A internal NMOS switch designed to deliver up to 120  
mA at 16V from a Li-Ion battery.  
The device's synchronous switching operation (no external  
Schottky diode) at heavy-load, and non-synchronous switch-  
ing operation at light-load, maximizes power efficiency.  
Features  
18V@80 mA from 3.2V input  
5V@280 mA from 3.2V input  
No external Schottky diode required  
85% peak efficiency  
Soft start  
True shutdown isolation  
True shutdown function by synchronous FET and related cir-  
cuitry ensures input and output isolation.  
Stable with small ceramic or tantalum output capacitors  
Output short-circuit protection  
A programmable soft-start circuit allows the user to limit the  
amount of inrush current during startup. The output voltage  
can be adjusted by external resistors.  
Feedback fault protection  
Input under-voltage lock out  
The LM4510 features advanced short-circuit protection to  
maximize safety during output to ground short condition. Dur-  
ing shutdown the feedback resistors and the load are discon-  
nected from the input to prevent leakage current paths to  
ground.  
Thermal shutdown  
0.002 µA shutdown current  
Wide input voltage range: 2.7V to 5.5V  
1.0 MHz fixed frequency operation  
Low-profile 10–pin LLP package (3mm x 3mm x 0.8mm)  
The LM4510 is available in a 10-pin thermally enhanced  
Leadless Leadframe Package: LLP-10.  
Applications  
Organic LED Panel Power Supply  
Charging Holster  
White LED Backlight  
USB Power Supply  
Class D Audio Amplifier  
Camera Flash LED Driver
