製品概要
The MAX1800 evaluation kit (EV kit) accepts 1.8V to 5.5V battery voltages and provides all of the output voltages required in digital still cameras (DSC). The EV kit consists of the MAX1800 multi-output master converter and the MAX1801 slave step-up converter.
The EV kit provides 10 separate output voltages. The MAX1800 provides one main-system step-up converter (3.3V/400mA), one linear regulator for the DSP core (1.8V/200mA), one step-up converter for the backlight (7V/100mA), three flyback outputs for the CCD (14.3V/10mA, 5V/50mA, -8.15V/10mA), and three flyback outputs for the LCD (13.85V/10mA, 5V/50mA, -16.23V/10mA). In addition, the MAX1801 provides one step-up converter for the motor (5V/500mA).
The EV kit's outputs are adjustable and are suitable for applications running from 2- or 3-cell alkaline, NiCd, or NiMH batteries or from a single lithium-on (Li+) battery.
