The MAX25221 evaluation kit (EV kit) is a fully assem- bled and tested surface-mount PCB used to evalu- ate MAX25221 automotive 4-Channel TFT-LCD Power Supply with VCOM Buffer and MAX25220 automotive 4-Channel TFT-LCD Power Supply without VCOM. Each output rail (AVDD, NAVDD, VGON, VGOFF and VCOM) can be independently adjusted via I2C. The EV kit dem- onstrates the device’s features: adjustable output voltage, fault protection, VCOM temperature compensation, and non-volatile memory programming. The EV kit exposes an I2C interface which can operate in conjunction with the MINIQUSB+ adapter or a third party I2C master like a general-purpose microcontroller. The EV kit also includes Windows®-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the IC. The EV system includes both the EV kit and the MINIQUSB+ adapter board.
主要特征
- 2.65V to 5.5V Input Range
- Default Output Voltages
- 6.8V Output at 200mA (Boost Converter)
- -6.8V Output at -200mA (Inverting Regulator)
- 12V Output at 15mA (Positive-Charge Pump Regulator)
- -10V Output at 15mA (Negative-Charge Pump Regulator)
- -2.49V Output at 100mA (VCOM Buffer)
- Selectable Switching Frequency (2.1MHz or 420kHz) with Spread-Spectrum Option. (The EV kit compo- nents will fit the 2.1MHz frequency. Using 420kHz will need hardware change.)
- Dedicated GUI
- Full Sequencing Flexibility
- Proven PCB Layout
- Fully Assembled and Tested
