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 • Stable with small ceramic or tantalum output capacitors • Output short-circuit protection • Feedback fault protection • Input under-voltage lock out • 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) 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 switching operation at light-load, maximizes power efficiency. True shutdown function by synchronous FET and related circuitry ensures input and output isolation. 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. The LM4510 features advanced short-circuit protection to maximize safety during output to ground short condition. During shutdown the feedback resistors and the load are disconnected from the input to prevent leakage current paths to ground. 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

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LM4510SD	ABCD150	0	34175	0	0	4234000	1	1201409060
LM4510SDX	ABCD150	0	34175	0	0	4234000	1	1201409060

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
