LM4510 - Synchronous Step-Up DC/DC Converter

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.

Key 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. Features.
  • 18V@80 mA from 3.2V input 5V@280 mA from 3.2V input No external Schottky diode required.

LM4510 Synchronous Step-Up DC/DC Converter with True Shutdown Isolation October 2007 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 switchwww.DataSheet4U.com ing 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.
