Description

The MAX887 evaluation kit (EV kit) provides a 3.3V output voltage from a +3.5V to +11V input. It delivers up to 600mA and operates with up to 100% duty cycle for low dropout voltage. Typical efficiencies are 93% . The MAX887 features a low-current (2.5µA typ) shutdown mode, as well as current-mode operation for superior load and line response. Cycle-by-cycle current limiting protects the internal MOSFET and rectifier.

This EV kit is a fully assembled and tested surface-mount circuit board. It can be used to evaluate other output voltages by changing feedback resistors R1 and R2.
