Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community LM4510 SNVS533D – SEPTEMBER 2007 – REVISED NOVEMBER 2014 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 1.2-A internal NMOS switch designed to deliver up to 120 mA at 16 V from a LiIon battery.

The device's synchronous switching operation (no external Schottky diode) at heavy-load, and nonsynchronous switching operation at light-load, maximizes power efficiency.

True shutdown function by synchronous FET and related circuitry ensures input and output isolation.
