EJW5015A 2A, 40V Synchronous Step-Down Converter

General Description

The EJW5015A is a current mode monolithic buck switching regulator. Operating with an input range of 3.6V~40V,

The EJW5015A 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 EJW5015A guarantees robustness with short-circuit      protection, thermal protection, start-up  current   run-away

protection, and input under voltage lockout.

The EJW5015A  is available in 8-pin ESOP package, which provides a compact solution with minimal  external

components.  The  package  has an exposed pad for low thermal resistance.
