Scalable PWM Controller Delivers Unmatched Flexibility for Power-Hungry ASICs and Computing Designs
Intersil’s ISL8120 Combines Wide Input Voltage (2.97V to 24V), Current Sharing and Variable Phase Shifting to Create the World’s Most Scalable PWM Controller Solution.
MILPITAS, CA, April 10, 2008 – Intersil Corporation (NASDAQ Global Select:
ISIL), a world leader in the design and manufacture of high-performance analog
semiconductors, today announced the release of the
ISL8120
Dual Output or Variable Phase PWM Controller. This PWM controller features
proprietary current sharing technology which enables multiple versions of the
chip to be used in parallel for a cost-efficient dual output or n-phase PWM
controller solution that addresses a variety of specific design needs.
Each phase delivers up to 25A of output current, based upon MOSFET selection.
Each chip can be configured as two single-phase outputs or one dual-phase
output. With the ability of each ISL8120 to deliver two single-phase 25A outputs
or one dual-phase 50A output, designers determine the number of ISL8120s
required based on the number of voltage rails and output current levels that
need to be generated. Up to six ISL8120s can be used in parallel to deliver a
single 12-phase 300A output. The ISL8120’s integrated current sharing control
enables this unique scalability.
The ISL8120’s versatility is further increased by its ability to handle
industry-standard input voltages of 3V, 9V, 12V and 24V. In addition, the
device’s gate drive voltage ranges from 2.7V to 5.5V, featuring a low-side 2A/4A
5V drive and a 2A/2A 5V high-side drive. The controller can also perform
overcurrent sensing by DC resistance (DCR), Rds(on) or external sense resistance
(ESR) so that it can function in a broad variety of system architectures.
The ISL8120 also provides high accuracy by offering true differential remote
sensing. This is achieved by referencing from an individual node point directly
to ground and provides a higher degree of accuracy, allowing more precise
debugging of the layout.
Available now in a 32-lead QFN package, the ISL8120 is a perfect PWM controller
solution for datacomm or telecomm systems, RAID systems, power modules, power
supplies or industrial applications.
