JW5017S - JoulWatt

JW5017S 26V Synchronous Step-Down Converter

The JW®5017S is a current mode monolithic buck switching regulator. Operating with an input range of 4.5V~26V, the JW5017S delivers 1.2A 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 fr.
