ISL8205MEVAL1Z

5A Single Channel High Efficiency DC/DC Step-Down Power Module Evaluation Board

描述

The ISL8205MEVAL1Z evaluation board is designed to demonstrate the performance of the ISL8205M 5A single channel high efficiency DC/DC step-down power module. The board is by default set to be 1.2V output voltage with 1.6MHz switching frequency. Other output voltage values can be easily set by changing the jumper position. Switching frequency can be adjusted by changing the FS pin resistor.

The ISL8205M power module is a single channel synchronous step-down complete power supply, capable of delivering up to 5A of continuous current. Operating from a single 2.6V to 5.5V input power rail and integrating a controller, power inductor and MOSFETs, the ISL8205M can achieve up to 95% conversion efficiency. It also provides fast transient response with excellent loop stability as well as delivers output voltages as low as 0.6V. Switching frequency is also adjustable from 680kHz to 3.5MHz with either an external resistor or SYNC clock option. Selectable PFM mode can also be enabled to boost up light load efficiency to extend battery life. Other features include programmable soft-start, soft-stop, input undervoltage lockout, 100% duty cycle operation, over-temperature, overcurrent/short-circuit with hiccup mode, overvoltage, and negative overcurrent protection. It also has a dedicated enable pin and power-good flag that allow for easy system power rails sequencing.
