EC5015A -2A, 40V Synchronous Step-Down Converter

General Description

The EC5015A is a current mode monolithic buck switching regulator. Operating with an input range of 3.6V~40V, The EC5015A 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 EC5015A guarantees robustness with short-circuit     protection, thermal protection, start-up current run-away protection, and input under voltage lockout.

The EC5015A 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.
