Product Details

The MAX8848Z evaluation kit (EV kit) is a fully assembled and tested PCB that demonstrates the MAX8848Z high-performance negative charge pump. The MAX8848Z integrates an inverting charge pump and 7 current regulators capable of 24mA each to drive up to 7 white LEDs (WLEDs). The EV kit operates from a 2.7V to 5.5V input supply range and includes two pulse generators that are used for testing the MAX8847Y/MAX8848Y single-wire, serial-pulse dimming feature. The EV kit can also evaluate the MAX8847Y, MAX8847Z, and MAX8848Y. To evaluate the MAX8847Y, MAX8847Z, or MAX8848Y, request a free sample when ordering the EV kit.
