TDA4814 - Power Factor Controller

General Description

This device has a conditioning circuit for the internal power supply.

It allows standby operation with very low current consumption (less than 0.5 mA), a hysteresis between enable and switch-off levels and an internal voltage stabilization.

Key Features
