Description
The MAX8632 evaluation kit (EV kit) is designed to evaluate the MAX8632 DDR power-supply solution for notebooks, desktops, and graphics cards. The EV kit board produces VDDQ at the output of the synchronous PWM buck, VTT at the output of the sourcing/sinking LDO linear regulator, and VTTR at the output of the reference buffer.
The VDDQ output is preset to 1.8V and sources up to 10A. The VTT output is always VDDQ/2 and can source/sink up to 3A of peak current and 1.5A of continuous current. The VTTR output is also always VDDQ/2 and can source/sink up to 10mA.
The MAX8632 EV kit was conveniently designed with jumpers to select the OVP/UVP, TON, active-low SKIP, active-low STBY, and active-low SHDN modes. The board's default settings enable OVP (overvoltage protection), 300kHz switching frequency, low-noise PWM mode, VDDQ, VTT, and VTTR.
The VIN input accepts voltages from 7V to 20.5V and VDD requires a 5V bias supply.
