Product Details

The MAX25520 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB used to evaluate the MAX25520 automotive 2-Channel TFT-LCD Power Supply. The output rails, AVDD and NAVDD, can be programmed independently or programmed to track each other by using a specific configuration. Independent enable pins allow complete flexibility in powering up and down the outputs. The outputs are protected against overcurrent and undervoltage.

The device incorporates a fully integrated current-mode boost converter and a current-mode inverter with external rectifier. The EV kit operates at one of two switching frequencies, 420kHz or 2.1MHz. Operation at 2.1MHz makes possible very compact dual-output power supplies.

The EV kit demonstrates the device’s features of adjustable output voltage and fault protection.
