Family of digital power controllers delivers high efficiency solution for next-generation servers

New Products |
By eeNews Europe

The new family of digital controllers is based on CHiL’s proven digital platform offering full telemetry and programmability giving system designers a chance to differentiate their products with custom features. The family provides a fully compliant high speed serial bus to meet new industrial requirements. These 5, 6 and 8-phase dual output PWM controllers in which phases are flexibly assigned between loops 1 and 2 can be easily configured for Intel VR12, AMD SVI/PVI/G34 and feature switching frequency between 200 kHz to 1.2 MHz per phase.

The family of digital controllers offers efficiency improvements with features such as variable gate drive and dynamic phase control for best-in-class efficiency and programmable 1-phase or 2-phases for light loads. When used in conjunction with IR’s PowIRstage devices this family offers an optimized end-to-end solution delivering highest efficiency for next-generation servers.

Other key features of the new digital controllers include adaptive transient algorithm (ATA) on both loops to minimize output bulk capacitors and system cost, auto-phase detection with auto-compensation and per-loop protection features. In addition, the digital ICs offer I2C, SMBus and PMBus system interface for full telemetry and programmability that enables customers to differentiate their platforms in the market. Non-volatile memory for custom configuration, 3.3 V tri-state driver compatible, +3.3 V supply voltage and 0 to 85ºC ambient operation are also featured.

All CHiL digital power solutions are fully supported by IR’s Digital Power Design Center (DPDC) GUI at which facilitates design, development and deployment of the company’s digital solutions. Additionally, hardware support using IR’s proprietary SVID emulator system enables customers to emulate and monitor either Intel or AMD serial interface protocols, as well as high speed I2C communication.

Pricing ranges from $2.00 each for the IR3541 to $3.25 each for the IR3538 in 1,000 unit-quantities. Production orders are available immediately.
