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.
