LV14360 60-V, 3-A Step-Down Converter With High Light Load Efficiency

1 Features

3 Description

•

4.3-V to 60-V input range

The LV14360 is a 60-V, 3-A step-down regulator with

an integrated high-side MOSFET. With a wide input

range from 4.3 V to 60 V, the device is suitable for

various applications from industrial to automotive for

power conditioning from unregulated sources. The

quiescent current of the regulator is 300 µA in sleep

mode, which is suitable for battery-powered systems.

An ultra-low 1-μA current in shutdown mode can

3-A continuous output current

300-µA operating quiescent current

155-mΩ high-side MOSFET

Current mode control

Adjustable switching frequency from 200 kHz to 2

MHz

•

Frequency synchronization to external clock

Internal compensation for ease of use

High duty cycle operation supported

Precision enable input

1-µA shutdown current

Thermal, overvoltage, and short protection

8-pin HSOIC with PowerPAD^™package

further prolong battery life.

A wide adjustable

switching frequency range allows either efficiency or

external component size to be optimized. Internal loop

compensation means that the user is free from the

tedious task of loop compensation design. This also

minimizes the external components of the device. A

precision enable input allows simplification of

regulator control and system power sequencing. The

device also has built-in protection features such as

cycle-by-cycle current limit, thermal sensing and

shutdown due to excessive power dissipation, and

output overvoltage protection.

2 Applications

•

Industrial power supplies

Communications equipment and datacom modules

General purpose wide V_INregulation

The LV14360 is available in an 8-pin, 4.89-mm × 3.9-

mm HSOIC package with exposed pad for low

thermal resistance.
