EVQ4210-U-00B

EVQ4210-U-00B 40V, 100W Synchronous Buck-Boost Controller with I2C and Current Monitor, AEC-Q100 Qualified DESCRIPTION FEATURES The EVQ4210-U-00B Evaluation Board is designed to demonstrate the capabilities of MPS’ MPQ4210GU-AEC1.    The MPQ4210 is a synchronous, four-switch, buck-boost controller capable of regulating different output voltages with a wide input voltage range and high efficiency. It provides an I2C interface, which supports VOUT voltage programmability, VOUT slew-rate control, and output constant current limit programmability, making the MPQ4210 suitable for USB power delivery (PD) design in USB Type-C power supplies. The MPQ4210 uses valley current control in buck mode and peak current control in boost mode, providing fast load transient response and smooth buck-boost mode transient. The MPQ4210 provides forced continuous conduction mode (FCCM) and a programmable average current limit, which supports flexible designs for different applications. It also features programmable over-current protection (OCP) mode, programmable overvoltage protection (OVP) mode, and programmable VIN UVLO hysteresis. The MPQ4210 is available in a QFN-27 (5mmx5mm) package.

Connect the positive and negative terminals of the load( ≤ 3A) to the VOUT and GND pins, respectively. 2. Preset the power supply output voltage within the range 6V~40V, and then turn off the power supply. 3. Connect the positive and negative terminals of the power supply output to the VIN and GND pins, respectively. 4. Install the MPQ4210 GUI software, connect I2C cable from host computer to the board. (MPS provides USB to IC develop dongle for MPQ4210 GUI control) 5. Turn on the power supply. And then click Detect button on the GUI. 6. Normally the GUI will indicate the connection is OK. Then set MPQ4210 registers through I2C in following step: a. b. c. d. e. Set ILIM bits to 111b for >5A load current limit; Set 0x02h bit[2] to 1b before ENPWR=1; Set BB_FSW bit to 1b to get higher frequency in buck-boost mode. Set ENPWR=1 to enable MPQ4210 switching, default output voltage is 5V. If other output voltage is required, firstly set the REF bits (Vout=10*VREF), then write GO_BIT=1, MPQ4210 will change VOUT automatically.
