EJW5052C 1.5A, 20V Synchronous Buck LED Driver

Description

The EJW5052C is a current mode monolithic buck voltage converter. Operating with an input range of 4.5V-18V,

The EJW5052C  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 EJW5052C  guarantees  robustness  with  short circuit   protection,   thermal   protection, current run-away protection, and input   under voltage lockout. The  EJW5052C  is  available  in  a  6-pin  SOT23-6 package, which provides a compact solution with minimal external components.
