Features: The Future of Analog IC Technology MP24 95 Integrated 100V Load Dump Protection , 2A Step Down Regulator with Output Cu rrent Control DESCRIPTION The MP2495 i s a monolithic step-down switch mode co nverter with a programmable output curr ent limit and an integrated input overv oltage protection switch It achieves 2. 0A continuous output current over a wid e input supply range with excellent loa d and line regulation. The maximum outp ut current can be programmed by sensing current through the inductor DC resist ance (DCR) or an accurate sense resisto r. Fault condition protection includes cycle-by-cycle current limiting and the rmal shutdown. The MP2495 can survive h igh-voltage transients such as those fo und in automotive and industrial applic ations. The MP2495 requires a minimum n umber of readily available standard ext ernal components. The MP2495 is availab le in a 16-pin SOIC package. FEATURES • Replaces External Transorb • Inpu t Surge Protection Up to 100V • Programmable up to 2.0A Output Curr.

The Future of Analog IC Technology
MP2495
Integrated 100V Load Dump Protection, 2A Step
Down Regulator with Output Current Control
DESCRIPTION
The MP2495 is a monolithic step-down switch
mode converter with a programmable output
current limit and an integrated input over-
voltage protection switch It achieves 2.0A
continuous output current over a wide input
supply range with excellent load and line
regulation.
The maximum output current can be
programmed by sensing current through the
inductor DC resistance (DCR) or an accurate
sense resistor.
Fault condition protection includes cycle-by-cycle
current limiting and thermal shutdown.
The MP2495 can survive high-voltage transients
such as those found in automotive and industrial
applications.
The MP2495 requires a minimum number of
readily available standard external components.
The MP2495 is available in a 16-pin SOIC package.
