General Description
The MX846 is a 50 mA regulated output switched capacitor
Buck-Boost DC/DC Converter targeting portable, battery
powered devices. The MX846 supplies a high efficiency
regulated output voltage with a minimum number of external
components. The output is adjustable from 3 to 5 volts with an
accuracy of ±5%. The charge pump topology of the MX846
eliminates the need for an inductor making it ideal for low noise
applications.
With an operating range of 3 to 5 volts, and a typical shutdown
current of 1 µA, the MX846 is an optimum choice for portable
battery powered devices. A 1MHz switching frequency enables
the use of small charge pump and filter capacitors to meet the
demands of size sensitive applications.
