20V Synchronous Step-Down Converter - H&M Semiconductor
Description
03
2A, 20V Synchronous Step-Down Converter
FEATURES
DESCRIPTION
The MP1482 is a current mode monolithic buck switching regulator.
Operating with an input range of 4.
6-20V, the MP1482 delivers 2A of continuous output current with two integrated N-Channel MOSFETs.
The internal synchronous power switches provide high efficiency without the use of an external Schottky diode.
At light loads, regulators operate in low frequency to maintain high efficiency and low output ripple.
Current mode control provides tight load transient response and cycle-by-cycle current limit.
The MP1482 guarantees robustness with short-circuit protection, thermal protection, start-up current run-away protection, and input under voltage lockout.
The MP1482 is available in an 8-pin SOP package, which provides a compact solution with minimal external components.
