DESCRIPTION
The JW ® 5027 is a current mode monolithic buck
voltage converter. Operating with an input range
of 3.7V-24V, the JW5027 delivers 2A of
continuous output current with two integrated
N-Channel MOSFETs. At light loads, regulators
operate in low frequency to maintain high
efficiency and low output ripple.
The JW5027 guarantees robustness with short
circuit protection, thermal protection, current
run-away protection, and input under voltage
lockout.
The JW5027 is available in a 6-pin SOT23
package, which provides a compact solution with
minimal external components.
