MAX25169EVKIT#

MAX25169 evaluation kit (EV kit) demonstrates the MAX25069/MAX25169 IC, which is a highly integrated power supply plus LED backlight driver for automotive TFT-LCD applications. The EV kit is a Fully assembled and tested surface-mount PCB that provides a complete power-management solution for automotive displays. The EV kit demonstrates one current-mode boost converter with sequencing switch (HVINP–AVDD), one current mode inverting regulator (NAVDD), positive and negative gate-voltage controllers (VGON), and (VGOFF), and a boost converter that powers a six-string LED driver.

• 2.65 to 5.5V i/p range for TFT-LCD power section, 4.5 to 36V i/p range for LED driver section
• Selectable switching frequency (2.1MHz or 420KHz)with spread-spectrum option on TFT power section
• 2.2MHz/400KHz resistor-programmable switching frequency with spread-spectrum on LED driver
• Synchronization input for 400KHz to 2.2MHz switching frequency
• On-board programmability for other values in the available set
• Phase-shift dimming option
• Demonstrates cycle-by-cycle current limit and thermal-shutdown features
• Demonstrates wide dimming ratio, designed to show thermal foldback function
• Demonstrates hybrid dimming for better EMI and acoustic performance and higher dimming ratio
• I2C programmability
