The HC1086 is a high efficiency synchronous, 3 channel PWM step-down DC/DC converter working under an input voltage range from 2.5V to 5.5V. It integrates three PWM synchronous step-down DC-DC converters. 100% duty cycle capability extends battery life in portable devices, while the quiescent current (one channel) is 200 µ A with no load, and drops to < 1 µ A in shutdown.
Each DC-DC converter has independent enable input and short-circuit protection allowing versatile power sequence combination.
The HC1086 converters are available in the industry standard QFN44-24L packages (or upon request).
