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.
