10W ~ 15W external LED constant current power supply solution

The TOP Switch-JX series is the latest generation of products launched by PI for the LED external adapter market. It is an integrated switching power supply chip that can convert the control pin input current into a high-voltage power MOSFET switch output duty cycle. In addition to features such as high-voltage start-up, cycle-by-cycle current limit, loop compensation circuit, automatic restart, and thermal shutdown, it also integrates a number of additional functions that can reduce system costs, improve power supply performance, and design flexibility.
