The MAX16927 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that provides the voltages and features required for display systems in automotive applications. The EV kit contains a buck converter, boost converter, Cuk converter, positive gate-voltage linear regulator, negative gate-voltage linear-regulator controller, DAC-adjustable positive VCOM buffer, and DAC-adjustable negative VCOM buffer.
The EV kit operates from +6V to +16V or +3V to +5.5V DC supply voltage ranges. The EV kit’s default input range is configured to +6V to +16V. The buck converter (VCC3) is configured for a +3.3V output providing at least 2A. The boost converter (VSH) is configured for a +7V output providing at least 200mA. The Cuk converter (VSL) is configured for a -7V output providing at least 100mA. The positive gate-voltage linear regulator (VGH) is configured for a +12V output providing at least 20mA. The negative gate-voltage linear-regulator controller (VGL) is configured for a -12V output providing at least 20mA. The negative VCOM buffer (VCOML) is DAC adjustable between -1V and +1V and can source or sink 10mA. The positive VCOM buffer (VCOMH) is DAC adjustable between +2.5V and +4.5V and can source or sink 100mA.
The EV kit provides an on-board USB interface circuit to communicate with the SPI interface circuits in the MAX16927 IC.
The EV kit also includes Windows® 2000-, Windows XP®-, and Windows Vista®-compatible software that provides the user interface for exercising the features of the IC. The program is menu driven and offers a graphical user interface (GUI).
