JW5052S - JoulWatt

JW5052S Step-Down Converter

The JW®5052S is a current mode monolithic buck voltage converter. Operating with an input range of 3.7~18V, the JW5052S delivers 2A 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 JW5052S guarantees robustness with short circuit prot.
