3A, 50V, 100kHz Step-Down Converter
with Programmable Output OVP Threshold
The Future of Analog IC Technology
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
The MP2497-A requires a minimum number of
readily available standard external components.
The MP2497-A is available in SOIC8E
