ISL6244 Product details

Description

ISL6244CR (32 LEAD QFN 5x5) IOUT The current carried out of this pin is proportional to output current and can be used to incorporate output voltage droop and/or load sharing.The scale factor is set by the ratio of the ISEN resistors and the lower MOSFET rDS(ON).If droop is desired, connect this pin to FB.When not used for droop or load sharing, simply leave this pin open.24 PWM4 23 ISEN4 22 ISEN1 21 PWM1 20 PWM2 19 GND 18 ISEN2 17 ISEN3 TOP VIEW PGOOD 25 VID3 VID4 GND VFF NC EN 27 32 V

Features

of this controller IC include Dynamic VIDTM technology allowing seamless on-the-fly VID changing without the need of any external components. Battery “feed-forward” is provided to allow for traditional control schemes over total input voltage variation. Output voltage “droop” or active voltage positioning is optional. When employed, it allows the reduction in size and cost of the output capacitors required to support load transients. A threshold-sensitive enable input allows the use of an extern.
