EJW5068A 1.5A, 20V Synchronous Buck LED Driver


The EJW5068A is  a monolithic  buck  switching regulator based      on I2 architecture for fast transient response. Operating with an input range of  4V~23V,  EJW5068A  delivers  8A  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,   the regulator  operates  in  low  frequency  to  maintain high efficiency and low output ripples. EJW5068A guarantees        robustness with output short protection, thermal protection,

Current run-away protection,  and  input  under  voltage lockout. EJW5068A  is   available  in QFN3X3-20 package,

which  provide  a  compact  solution  with  minimal external components.
