Applications/Uses

Description

The MAX668 evaluation kit (EV kit) combines a constant-frequency, pulse-width-modulation (PWM) step-up controller with an external N-channel MOSFET and Schottky diode to provide a regulated output voltage. The EV kit accepts a +3V to VOUT input and converts it to a +12V output for currents up to 1A, with greater than 90% conversion efficiency. The EV kit operates at 500kHz, allowing the use of small external components.

The MAX668 EV kit is a fully assembled and tested surface-mount circuit board. This EV kit can also be configured for the application circuits listed in the EV Kit Application Circuit Capabilitiestable. For input voltages below 3V and down to 1.8V, replace the MAX668 with a MAX669. The MAX669 must always operate in bootstrapped mode (JU2 shunt across pins 1 and 2).
