Power推出一款新的IC CAPZero

CAPZero is an IC that completely eliminates the power dissipated by X capacitor discharge resistors. CAPZero is a two terminal device that can be added to any power supply with X capacitor discharge resistors to decrease no-load consumptions and provides more standby power. It is a simple product that easily meet safety requirements.

When AC voltage is applied, CAPZero blocks current flow in the X capacitor safety discharge resistors, reducing the power loss to less than 5 mW or essentially zero at 230 VAC. When AC voltage is disconnected, CAPZero automatically discharges the X capacitor by connecting the bleed resistors in parallel. This operation allows total flexibility in the choice of the X capacitor to optimize differential mode EMI filtering and reduce inductor costs with no change in power consumption.

The simplicity and ruggedness of the two terminal CAPZero chip makes it an ideal choice in systems designed to meet EuP Lot 6 requirements.

Applications
