LinkSwitch-TNZ Off-line Switcher ICs

Power Integrations LinkSwitch-TNZ Off-line Switcher ICs are designed to provide lossless zero-cross signal generation and support buck, buck-boost, and flyback topologies. These ICs offer more design flexibility than discrete implementations which reduces component count by 40% or higher. The LinkSwitch-TNZ ICs feature soft-start, auto restart, output Over Voltage Protection (OVP), line input Over Voltage Protection (OVL), and hysteretic Over-Temperature Protection (OTP). These ICs incorporate a 725V power MOSFET, an oscillator, a high-voltage switched current source, frequency jittering, hysteretic thermal shutdown, and input/output overvoltage protection circuitry. The LinkSwitch-TNZ ICs consume <100µA current in standby that results in power supply designs to meet no-load and standby regulations worldwide. These ICs are used in applications such as home and building automation, dimmers, switches and sensors with/without neutral wire, appliances, and IoT/industrial controls.
