JW5057C Parameters Subject to Change Without Notice 17V/3A Sync. Step-Down Converter DESCRIPTION The JW®5057C is a current mode monolithic buck voltage converter. Operating with an input range of 4.5V-17V, the JW5057C delivers 3A of continuous output current with two integrated N-Channel MOSFETs. At light loads, regulators operate in low frequency to maintain high efficiency and low output ripple. The JW5057C guarantees robustness with short circuit protection, thermal protection, current run-away protection, and input under voltage lockout. The JW5057C is available in a 6-pin SOT23-6 package, which provides a compact solution with minimal external components.
