AC / DC converter unit

BP5034A5

The BP5034A5 is an AC / DC converter that provides a direct current (5V) from commercial power supply (100V , AC),
with a small number of external components required. Using this IC, a compact microcontroller-based device can be
configured without a transformer.

Applications
Power supplies for vacuum cleaners, rice cookers, electric pots, steam irons, telephones, electric heaters, lighting equip­ment, gas leakage alarms, and sensors

Features

1) Smaller and lighter than transformers.

2) Wide range of input voltage (80  120V , AC).

3) Few external components required.

4) Power supply board is resistant to impacts because
a transformer is not used.

5) The hybrid IC allows easy assemblage of compo­nents.

∗1 Pin 6 is the COMMON pin and is connected internally to pin 5.

Use eitcher both, or one or the other, as the COMON pin. Keep
open the other pins that are not used.

Application example
Example of a vacuum cleaner application
The diode bridge, which draws out a zero-cross signal, is not required if a zero-cross signal is not used.
