Product Details
The MAX1855 evaluation kit (EV kit) demonstrates a high-power, dynamically adjustable notebook CPU power-supply application circuit. The MAX1855 DC-DC converter steps down high-voltage batteries and/or AC adapters, generating a precision, low-voltage CPU core VCC rail. The MAX1855 EV kit is designed for CPU core applications requiring a voltage-positioned supply. Voltage positioning and a high-DC-accuracy control loop decrease full-load power dissipation and reduce the required number of output capacitors.
This fully assembled and tested circuit board provides a digitally adjustable 0.6V to 1.75V output voltage from a +7V to +24V battery input range. It delivers up to 18A output current. The EV kit operates at 300kHz switching frequency and has superior line- and load-transient response.
This EV kit can also be used to evaluate the MAX1716 (0.925V to 1.6V output) and the MAX1854 (0.925V to 2.0V output).
