SENSE

Description

MOSFETs' R

DS(ON)

The PM6675AS device consists of a single high

efficiency step-down controller and an

independent low drop-out (LDO) linear regulator.

– Negative current limit

– Latched OVP and UVP

– Soft-start internally fixed at 3 ms

– Selectable pulse skipping at light load

– Selectable No-audible (33 kHz) pulse skip

mode

– Ceramic output capacitors supported

– Output voltage ripple compensation

– Output soft-end

The constant on-time (COT) architecture assures

fast transient response supporting both

electrolytic and ceramic output capacitors. An

embedded integrator control loop compensates

the DC voltage error due to the output ripple.

Selectable low-consumption mode allows the

highest efficiency over a wide range of load

conditions. The low-noise mode sets the minimum

switching frequency to 33 kHz for audio-sensitive

applications. The LDO linear regulator can sink

and source up to 2 Apk. Two fixed current limit

( 1 A- 2 A) can be chosen.

■ LDO regulator section

– Adjustable 0.6 V to 3.3 V output voltage

– Selectable 1 Apk or 2 Apk current limit

– Dedicated power-good signal

– Ceramic output capacitors supported

– Output soft-end

An active soft-end is independently performed on

both the switching and the linear regulators

outputs when disabled.

Applications

■ Industrial application on 24 V

■ Graphic cards

■ Embedded computer systems
