| 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 evaluation board is designed to provide adjustable output voltage from a single Li-Ion battery. By default, output voltage is set to 16V. Please refer to the datasheet and application note for additional information.

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.
