应用/用途

描述

The MAX1802 evaluation kit (EV kit) accepts +3.3V to +11V battery voltages and provides all of the output voltages required in digital still cameras (DSC). This EV kit consists of the MAX1802 multi-output master converter and the MAX1801 slave step-up converter.

The MAX1802 EV kit provides 10 separate output voltages. The MAX1802 provides one main system step-down converter (+3.3V/1A), one DSP core step-down (+1.8V/400mA), one step-up converter for the backlight (+7V/100mA), three flyback outputs for the CCD, and three flyback outputs for the LCD. In addition, the MAX1801 provides one general-purpose step-up converter (+12V/100mA).

The MAX1802 EV kit's outputs are adjustable and are suitable for applications running from 4-cell alkaline, NiCd, or NiMH batteries, or from lithium ion (Li+) batteries (1 or 2 cell).
