PIN CONFIGURATION
DESCRIPTION
The JW5015 is a current mode monolithic buck
switching regulator. Operating with an input range
of 3.6-40V, the JW5015 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 JW5015 guarantees robustness with
short-circuit protection, thermal protection,
start-up current run-away protection, and input
