Abstract

The invention discloses an integrated module with a power-saving driving DC power supply chip for alternating current wide voltage input, it uses an external half-wave rectifier diode, rectifying thealternating current into a non-inverting pulse current, At each in-phase pulse, The supply of electricity will only be carried out within a very short period of time and within a low voltage area, A low-frequency synchronous oscillation power supply is carried out at a low-voltage position by utilize a synchronous zero detection clamp of an alternating current inside that chip, and the low-frequency synchronous oscillation power supply of the alternating current is carried out, and then dynamically charging the external energy storage capacitor by using the on-chip low frequency discontinuouspulse, to maintain the relay and the power supply capability of the external MCU, The chip combines the relay power saving driving unit and LDO voltage stabilizing circuit unit, and then combines thechip with several thyristors to become a highly integrated module for small household appliances, which has the advantages of small volume, easy processing, no EMI/EMC interference, no heat, low cost,high efficiency, and conforms to the European Union ERP standard.

Description
