STMicroelectronics AC/DC Offline Switcher IC, Flyback, 10W, DIP-7
STMicroelectronics 10W AC/DC offline switcher IC with flyback topology. Features 800V power section, DIP-7 package, and low EMI.
The STMicroelectronics AC/DC Offline Switcher IC is a highly integrated offline converter designed for efficient power management. Featuring an 800V avalanche ruggedness power section and a built-in PWM controller, this device delivers reliable performance for a variety of applications. It is specifically engineered to power itself directly from the rectified mains, which eliminates the need for an auxiliary bias winding and simplifies circuit design.
Key Features and Benefits
This advanced switcher IC incorporates a range of protective and efficiency-enhancing features:
- Advanced Protection: Includes user-defined overcurrent limiting, protection against feedback network disconnection, and hysteretic thermal shutdown to ensure safe operation under fault conditions.
- Soft Start and Auto Restart: On-board soft-start prevents inrush current issues, whilst the safe auto-restart functionality recovers the device automatically after a fault.
- Low EMI and Standby Power: PWM operation with frequency jittering reduces electromagnetic interference (EMI) filter costs. Burst mode operation ensures very low consumption, meeting stringent energy-saving regulations with standby power of less than 30mW at 230V AC.
Specifications
Designed in a compact DIP-7 package for through-hole mounting, this IC supports both isolated and non-isolated configurations. It operates at a switching frequency of 60kHz and handles input voltages ranging from 85V AC to 265V AC, making it suitable for global power grid compatibility. With a maximum power rating of 10W and a robust operating temperature range of -40°C to 150°C, this switcher IC is a versatile solution for modern electronics.
