Product details
Compared with the traditional discrete solution, used in automobile power LinkSwitch ™ - TN2 series IC greatly reduced the number of components.Using the integrated LinkSwitch - TN2 IC design has high reliability, without using optoelectronic isolator.The product series support step-down, buck - boost and flyback converter topology.Each device On a single chip IC used a 750 V power MOSFET, oscillator, On/Off control, one for IC implementation from the power supply of high voltage switch the current source, frequency modulation, fast cycle (by) current limit, hysteresis heat shut Off and the output and input over-voltage protection circuit.
LinkSwitch - TN2 IC current consumption in standby mode, so when the 400 VDC input power supply design meets < 50 mW no-load input.Perfect protection feature to ensure power supply safe and reliable operation, in case of input and output overvoltage fault, overheating fault device, voltage imbalance, and the power supply output overload or short circuit fault protection devices and the whole system.
