JW5015B

Parameters Subject to Change Without Notice JW5015B 2A, 40V Synchronous Step-Down Converter FEATURES 3.6 V to 40 V operating input range 2A output current Up to 94% efficiency High efficiency (>78%) at light load Internal Soft-Start Fixed 100kHz Switching frequency Input under voltage lockout Low EMI noise Available in thermally enhanced ESOP8 package Current run-away protection Short circuit protection Thermal protection APPLICATIONS Distributed Power Systems Car charger FPGA, DSP, ASIC Power Supplies Green Electronics/ Appliances Networking Systems Notebook Computers DESCRIPTION The JW5015B is a current mode monolithic buck switching regulator. Operating with an input range of 3.6V~40V, the JW5015B 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, the regulator operates 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 JW5015B guarantees robustness with short-circuit protection, thermal protection, start-up current run-away protection, and input under voltage lockout. The JW5015B 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.
