MP2497-A

MP2497-A 3A, 50V, 100kHz Step-Down Converter with Programmable Output OVP Threshold The Future of Analog IC Technology DESCRIPTION The MP2497-A is a monolithic step-down switch mode converter with a programmable output current limit. The MP2497-A is the high efficiency version of MP2497. It has fast switching speed thus the switching loss is greatly reduced. It achieves 3A continuous output current over a wide input supply range with excellent load and line regulation. An internal 2-4ms soft start prevents inrush current at turning on. And it is capable of providing output line drop compensation. Fault condition protection includes hiccup current limit and short circuit protection, programmable output over voltage protection and thermal shutdown. The MP2497-A requires a minimum number of readily available standard external components. The MP2497-A is available in SOIC8E package.
