Multi-Resonance AC/DC Converter IC

MB3873

■ DESCRIPTION

The MB3873 is a pulse frequency modulation (PFM) type multi-resonance AC/DC converter IC providing soft

switching functions in a more compact, higher-efficiency, low-noise package.

Since this product allows reduced number of the components and reduced size of the transformer, it is also

compatible with the miniaturization of AC adaptor.

The product retains the multi-resonance for the non-load, over-load and load short-circuit over the wide range of

input voltage, making it the appropriate IC for the small-sized AC adaptor.

■ FEATURES

• Operating power supply voltage : 10V to 28V

• Operating current : 2.5mA typ.

• Low standby current : 400µA typ.

• Control frequency range : 10kHz to 800kHz

• Operating temperature range : −30°C to +105°C

• Soft start circuit on-chip

• Overvoltage detection circuit on-chip
