Product Overview

The LM4510SD/NOPB is a synchronous step-up DC-to-DC Converter with true shutdown isolation and a 1.2A internal NMOS switch designed to deliver up to 120mA 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.
  • No external Schottky diode required
