DESCRIPTION

The JW®H5140 and JW®H5140F is a monolithic

buck switching regulator based on constant

on-time control (COT) for fast transient response.

Operating with a wide input voltage range of

6V~100V, the JW®H5140 and JW®H5140F

delivers 0.6A of continuous output current with

two integrated MOSFETs. Constant on-time

control mode control provides tight load transient

response and cycle-by-cycle current limit. At light

loads, JWH5140 operates in low frequency to

maintain high efficiency, while JWH5140F

operates in continuous current mode for

frequency sensitive application.

The JWH5140 and JWH5140F guarantees

robustness with short-circuit protection, thermal

protection, current run-away protection, and

input under voltage lockout.

The JWH5140 is available both in ESOP8 and

DFN4X4-8 packages, and the JWH5140F is

available both in ESOP8 and DFN4X4-8

packages which provides a compact solution with

minimal external components.
