Analog Devices (ADI) introduces the MAX16602 and MAX20790 chipset, providing advanced self-protection and power features for voltage regulation. This chipset boasts impressive efficiency, exceeding 95%, and is capable of supporting designs ranging from 60A to 800A. The MAX16602 is a dual-output voltage regulator chipset designed specifically for VR13.HC and AI cores. Meanwhile, the MAX20790 is a smart power-stage IC that integrates current and temperature sensors.
To facilitate evaluation, ADI offers the MAX16602CL8 evaluation kit (EV kit), which comes fully assembled and tested. This surface-mount circuit board includes all the necessary components to assess the performance of the MAX16602 and MAX20790. The MAX16602 is a PMBus®-compatible controller packaged in a 56-pin, 7mm x 7mm QFN. It generates eight pulse-width modulated (PWM) control signals or phases. The EV kit itself is an 8-phase multiphase synchronous buck converter, featuring 2-phase coupled inductors that reduce the effective inductor value and size while minimizing ripple current. This design choice reduces the required output capacitance and improves transient response.
Furthermore, the EV kit also demonstrates the capabilities of the MAX20790 smart power-stage IC. This IC combines monolithic integration with advanced packaging technology, enabling high-switching frequencies with significantly lower losses compared to traditional implementations. For the main output rail, there are eight MAX20790 devices available.
In conclusion, ADI's MAX16602 and MAX20790 chipset provides cutting-edge self-protection and power features for voltage regulation. With its high efficiency, wide range of support, and advanced functionalities such as temperature monitoring and overcurrent protection, this chipset is a reliable choice for various applications.
