THX208 PDF – PWM Switching Power Supply Controller – THX

Part Number: THX208

Function: High-performance current-mode PWM controller

Manufacturesr :

Package: SOP8-6D Type

Image: THX208


Designed for Cost-effective AC / DC converter designs. In Within 85V -265V wide voltage range provides near 4W Continuous output power. Optimized and highly reasonable circuit Designed to combine high performance and low cost bipolar production workers Yi, the maximum extent to save the overall cost of the product. The power supply controller can operate in a typical flyback circuit Topology to form a simple AC / DC converter.
