Description

   The MAX1573 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board. The EV kit contains the MAX1573, a white LED driver with a high-efficiency charge pump. The EV kit accepts a 2.7V to 5.5V input voltage and drives up to 4 white LEDs with regulated constant current for uniform intensity. The MAX1573 runs at 1MHz fixed frequency, allowing tiny external components. An EV kit is available for both the UCSP and the TQFN packages.
