MAX16602 and MAX20790 Chipset

ADI's MAX16602 and MAX20790 chipset achieves greater than 95% efficiency and supports designs from 60 A to 800 A. This high-current multiphase voltage regulator chipset offers advanced self-protection and power features, including accurate temperature monitoring and fast overcurrent protection.

MAX16602: VR13.HC and AI cores dual-output voltage regulator chipset

MAX20790: Smart power-stage IC with integrated current and temperature sensors

The MAX16602CL8 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains all of the components necessary to evaluate the MAX16602 and MAX20790. The MAX16602 is a PMBus®-compatible, multiphase voltage regulator controller for AI cores or Intel® VR13.HC server CPUs. The IC is packaged in a 56-pin, 7 mm x 7 mm QFN. The controller generates eight pulse-width modulated (PWM) control signals or phases. The EV kit is an 8-phase multiphase synchronous buck converter that uses 2-phase coupled inductors, which reduce the effective inductor value and size without excessive ripple current, thus reducing the required output capacitance and improving transient response.

The EV kit also demonstrates the full functionality of the MAX20790 smart power-stage IC. The IC has monolithic integration and advanced packaging technology, allowing high-switching frequencies with significantly lower losses than conventional implementations. There are eight MAX20790 devices for the main output rail.

Features

• Coupled inductor technology allows for switching at a lower frequency
• Advanced power packaging with excellent thermal performance and dual side cooling enables high-density designs
• Extensive telemetry reporting through PMBus allows digital programming to monitor temperature, input voltage, current, and power
