The LED driver optimized for low-power lighting applications is based on a flyback circuit architecture design and can drive multiple LED loads within a universal AC input voltage range. It is an ideal product for LED lighting drivers.
PT4204 benefits from the transformer primary side inductive constant current control technology, without the need for an external feedback loop, and the system solution is simple and reliable. The optimized current compensation function ensures that the load current remains constant within the input voltage range of 85VAC~265VAC, and the inductance compensation function ensures that the LED load current does not change with the transformer winding inductance.
Package type: SOP8
Typical application: suitable for 1W~5W LED lighting products
