The MAX1685 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains a pulse-width-modulated (PWM), step-down DC-DC converter. The EV kit provides a +3.33V output voltage from a +3.5V to +14V input source. It delivers up to 1A output current. The MAX1685 features internal MOSFET switches, low dropout voltage (100% duty-cycle operation), and an accurate +1.25V reference.
The MAX1685 EV kit provides low quiescent current, synchronous rectification, and high efficiency (up to 95%) for maximum battery life. Operation at 600kHz allows the use of a tiny surface-mount inductor.
The MAX1685 EV kit can also be used to evaluate the MAX1684, which operates at 300kHz and has slightly higher efficiency than the MAX1685.
