MAX25520EVKIT#

MAX25520EVKIT 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 features of adjustable output voltage and fault protection.

• Input voltage range from 2.6V to 5.5V
• O/p voltage in tracking mode: 6.8V at 200mA(boost converter), -6.8V at -200mA(inverter regulator)
• Synchronous boost provides positive o/p at upto 10.5/200mA, inverter o/p upto -10.5/-200mA
• Spread spectrum
• UV diagnostic on all o/ps and fault detection
• Complete sequencing flexibility
• Operating temperature range from -40°C to 125°C
