Description
The HX1106 is a high efficiency synchronous,
dual channel PWM step-down DC/DC converter
working under an input voltage range of 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 HX1106 converters are available in the
industry standard DFN3*3-10L packages (or
upon request).
