Products Detail

The LinkSwitch-TN2 family integrates a high-voltage power MOSFET switch with a power supply controller in one device. It supports buck, buck-boost, and flyback topologies with features including selectable current limit, frequency jittering for reduced EMI, comprehensive system-level protection (auto-restart for faults, OVP, OVL, OTP), and ultra-low standby consumption. Designs achieve high efficiency across load ranges, meet global energy regulations, and use low-cost off-the-shelf inductors.
