Evaluation Kits (1)
The MAX8550 evaluation kit (EV kit) is designed to evaluate the MAX8550 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 2.5V and sources up to 12A. 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 MAX8550 EV kit was conveniently designed with jumpers to select the OVP/UVP, TON, SKIP-bar, STBY, and SHDN_-bar modes. The board's default settings enable OVP (overvoltage protection), 600kHz switching frequency, low-noise PWM mode, VDDQ, VTT, and VTTR.
The VIN input accepts voltages from 9V to 20V and VDD requires a 5V bias supply.
The EV kit comes with the MAX8550 installed. Contact the factory for free samples of the MAX8550A or MAX8551 to evaluate these parts.
