DESCRIPTION
The JW®5361, JW®5361M, JW®5361F and
JW®5361FM are monolithic buck switching
regulators based on I2 architecture for fast
transient response. Operating with an input range
of 4.5V~18V, JW5361, JW5361M, JW5361F and
JW5361FM deliver 3A 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 load, JW5361 and
JW5361M operate in low frequency to maintain
high efficiency.
JW5361, JW5361M, JW5361F and JW5361FM
guarantee robustness with output short protection,
thermal protection, current run-away protection
and input under voltage lockout.
JW5361, JW5361M, JW5361F and JW5361FM
are available in SOT23-6 package, which
provides a compact solution with minimal external
components.
