DS2410 Ver 1.0 Apr. 2009 1.6A, 500KHz Synchronous S t e p - u p C o n v e rt e r

DESCRIPTION

The EUP2410 is a highly efficient, synchronous, fixed frequency, current-mode step-up converter with output to input disconnect. When EUP2410 is disabled, the internal conduction path from SW to OUT is fully blocked and the OUT pin is isolated from the battery. This output disconnect feature reduces the shutdown current to typically only 50nA. The 500KHz switching frequency allows for smaller external components producing a compact solution for a wide range of load currents. Highly integration and internal compensation network minimizes as 5 external components, N-Channel switch and P-Channel Synchronous switch integration will greatly improve converter efficiency. Internal soft-start function al so reduce inrush current. The EUP2410 regulates the output voltage up to 6V from either a 2-cell NiMH/NiCd or a single-cell Li-Ion battery. The EUP2410 is offered in a thin SOT23-5 package. Typical Application Circuit
