The MAX1582/MAX1582Y utilize 1MHz current-mode PWM control to allow small input and output capacitors and a small inductor, while minimizing ripple on the input supply and avoiding interference to sensitive circuitry in the equipment. Integrated overvoltage protection (27V for the MAX1582 and 18V for the MAX1582Y) eliminates the need for an external zener diode to protect the IC from open circuit. Flexible dimming control utilizes either an analog control signal or direct digital PWM control without external RC filtering. This also increases dimming accuracy at low brightness levels. The PWM dimming signal can be any frequency from 200Hz to 200kHz. Softstart eliminates inrush current during startup. The MAX1582/MAX1582Y are available in tiny 4 4 chip-scale (UCSPTM) and 12-pin thin QFN packages. |
