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.
