The LYT2003D from Power Integrations is a highly integrated offline switcher IC that simplifies the design of low-power Constant Current (CC) LED drivers. It eliminates the need for optocouplers and secondary control circuitry, offering accurate output current regulation that compensates for variations in transformer inductance, external components, and input voltage.
This IC features a 725V switching power MOSFET, enabling clampless flyback designs. It operates at a nominal switching frequency of 85kHz and offers a maximum output power of 7W in ballast driver configurations and 6W in enclosed bulb configurations. The device is designed for energy efficiency, with no-load consumption typically less than 30mW.
The LYT2003D is housed in an 8-SOIC package and is suitable for surface mounting. It operates within a temperature range of -40°C to 150°C (TJ). Its advanced protection features include auto-restart for short-circuit faults and hysteretic thermal shutdown with automatic recovery.
Applications for the LYT2003D include LED bulbs, downlights, luminaires, ballasts, and T8 tubes. It is designed for cost-effective, small-size solutions.
