General description\nThe TEA1620P is a Switched Mode Power Supply (SMPS) controller IC that operates directly from the rectified universal mains. It is implemented in the high voltage EZ-HV? SOI process, combined with a low voltage BICMOS process. The device includes a high voltage power switch and ■ Designed for general purpose supplies\n■ Integrated power switch: 48 ? and 650 V\n■ Operates from universal AC mains supplies: 80 V to 276 V\n■ Adjustable frequency for flexible design\n■ RC oscillator for load insensitive regulation loop constant\n■ Valley switching for minimum switch-on loss\n■ ;
