The HC1061 is high efficiency synchronous, PWM step-down DC/DC converters working under an input voltage range from 2.2V to 5.5V. This feature makes the HC1061 suitable for single Li-Lon battery-powered applications. 100% duty cycle capability extends battery life in portable devices, while the quiescent current is 200μA with no load, and drops to <1μA in shutdown.
The internal synchronous switch is desired to increase efficiency without an external Schottky diode. The 1.2MHz/1.4MHz switching frequency allows the using of tiny, low profile inductors and ceramic capacitors, which minimized overall solution footprint.
The HC1061 converters are available in the industry standard SOT-23-5L power packages.
