Product Details

The MAX8596Z evaluation kit (EV kit) is a fully assembled and tested circuit board that evaluates the MAX8596Z white LED step-up DC-DC converter. The circuit operates from 2.6V to 5.5V and delivers an adjustable 0 to 25mA to drive up to 8 white LEDs in series.

The MAX8596Z EV kit comes configured for driving 6 white surface-mount LEDs; however, it can support up to 8 white LEDs. A 9th LED pad is provided to evaluate the MAX8595X/MAX8596X. The EV kit features the MAX8596Z's temperature derating function, but can be used to evaluate the MAX8595Z without this feature. Either IC provides the flexibility of controlling LED brightness through an external analog or a PWM dimming signal.

Applications

Cell Phones/Smartphones
e-Books and Subnotebooks
PDAs, Palmtops, and Wireless Handhelds
White LED Display Backlighting
