THX203H,High-Performance Current Mode PWM Controller, DIP-8

The THX203H is a high-performance current-mode PWM controller optimized for AC/DC transformer applications. Encased in a compact DIP-8 package, it integrates a high-voltage (700V) power switch tube and advanced current control mechanisms, making it ideal for efficient power conversion and regulation. The device delivers continuous output power of up to 12W, with peak capabilities reaching 18W, making it suitable for a range of industrial and consumer electronics.

Its energy-efficient design includes a low start-up current and automatic frequency reduction for reduced standby power consumption, enabling compliance with stringent energy standards. Comprehensive safety features such as overload protection, thermal shutdown, and under-voltage lockout ensure reliable operation in challenging conditions. With its high efficiency and robust protection, the THX203H is a versatile solution for power management in adapters, chargers, and open-frame systems like DVD and DVB players.
