2A, 40V Synchronous Step-Down Converter EJW5015A 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.
