Printer having energy storage device

A printer comprising:

• an energy storage device;
• a single stage power factor correction charger for charging the energy storage device and for providing a first DC voltage;
• a first DC-to-DC voltage converter for converting the first DC voltage to a second DC voltage;
• first printer electronics powered by the second DC voltage;
• a second DC-to-DC voltage converter for converting the first DC voltage to a third DC voltage,
• second printer electronics powered by the third DC voltage;
• and
• a mix signal application specific integrated circuit to provide a first pulse width modulated signal to the first DC-to-DC voltage converter to control the first DC-to-DC voltage converter based on a first feedback signal from the first DC-to-DC voltage converter and to provide a second pulse width modulated signal to the second DC-to-DC voltage converter to control the second DC-to-DC voltage converter based on a second feedback signal from the second DC-to-DC voltage converter,
• wherein the first voltage is less than the second voltage,
• wherein the first voltage is greater than the third voltage, and
• wherein the energy storage device provides power for a peak load condition of the first printer electronics,
• wherein the charger comprises:
• a full wave rectifier for receiving an AC voltage to provide a rectified signal;
• a capacitor coupled to the full wave rectifier to remove noise from the rectified signal;
• a pulse width modulation controller and power factor correction circuit coupled to the full wave rectifier and the capacitor;
• and
• a flyback converter coupled to the pulse width modulation controller and power factor correction circuit to provide the first DC voltage.
