EJW5057C 17V/3A Sync. Step-Down Converter

Description

The EJW5057C is a current mode monolithic buck voltage  converter.  Operating  with  an  input  range of      4.5V-17V, the EJW5057C 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 EJW5057C  guarantees  robustness  with  short circuit  protection,  thermal  protection, current run-away protection, and  input   under   voltage lockout. The  EJW5057C  is  available  in  a  6-pin  SOT23-6 package, which provides a compact solution with minimal external components.
