LinkSwitch™-TN2 Switcher IC
Power Integrations' LinkSwitch-TN2 energy efficient off-line switcher IC with integrated system level protection
Power Integrations' LinkSwitch-TN2 family of ICs for non-isolated off-line power supplies provide dramatically improved performance compared to traditional linear or cap-dropper solutions. Designs using the highly integrated LinkSwitch-TN2 ICs are more flexible and feature increased efficiency, comprehensive system level protection, and higher reliability. The device family supports buck, buck-boost, and flyback converter topologies. Each device incorporates a 725 V power MOSFET, oscillator, On/Off control for highest efficiency at light load, a high-voltage switched current source for self-biasing, frequency jittering, fast (cycle-by-cycle) current limit, hysteretic thermal shutdown, and output and input overvoltage protection circuitry onto a monolithic IC.
Design Examples:
- RDR-506 - 1.44 W Non-Isolated Buck Converter
- DER-508 - 4.75 W Dual Output Power Supply
- DER-507 - 175 mW Constant Voltage, Universal Input, Non-Isolated Buck Converter
- DER-574 - 1.65 W Non-Isolated Tapped Buck Power Supply
- Supports buck, buck-boost, and flyback topologies
- Low component-count buck converter
- Excellent load and line regulation
- Selectable device current limit
- 66 kHz operation with accurate current limit
- Allows the use of low-cost off-the-shelf inductors
- Reduces size and cost of magnetics and output capacitor
- Frequency jittering reduces EMI filter complexity
- Pin-out simplifies PCB heat sinking
- Major appliances
- Small appliances
- Internet of Things (IoT)
- Smart meters
