Description

The HX1006 is a high efficiency synchronous, dual channel PWM step-down DC/DC converter working under an input voltage range from 2.5V to 5.5V. It integrates two PWM synchronous step-down DC-DC converters. 100% duty cycle capability extends battery life in portable devices, while the quiescent current (one channel) is 200μA with no load, and drops to<1μA in shutdown.

Each DC-DC converter has independent enable input and short-circuit protection allowing versatile power sequence combination.

The HX1006 converters are available in the industry standard DFN3*3-10L packages (or upon request).

Applications

?  Digital cameras and MP3

?  Palmtop computers / PDAs
