Product details
LinkSwitch - TNZ series IC will power transformation and commonly used in the system clock and timing function of AC zero signal combination of lossless generation.Using high integration LinkSwitch - TNZ IC design has a score made greater applicability, can reduce the amount of 40% or more of the components.In addition to the small power to achieve more than 80% of the efficiency in the design of the flyback type, through the ON/OFF control implementation is extremely low power consumption of the light load, and can make more features (displays, wireless connectivity, sensors, etc.) in the system is active when the standby.The product series support step-down, buck - boost and flyback converter topology.
Each device on a single chip IC used a 725 v power MOSFET, oscillator, a high voltage switch to IC implementation from the power supply current source, frequency modulation, fast cycle (by) current limit, hysteresis heat shut off and the output and input over-voltage protection circuit.
LinkSwitch - TNZ IC consumption in standby mode of the current is less than 100 (including A, so that the power supply design conforms to the global standard of no-load and standby power consumption.MOSFET current limit mode through the bypass pin capacitance value choice.Choose high current limit point can provide maximum continuous output current, and low current limit points allows the use of very low cost small size surface-mount inductor.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.
The product features
The best performance and design suitability
- Generate a lossless zero signal
- Support the step-down type, buck - boost type and flyback topology
- In any input voltage and load adjustment precision are plus or minus 3%
- The optional components to current limit point
- Working frequency of 66 KHZ, and has accurate current limit point
- allows the use of commercially available off-the-shelf inductance low cost
- can reduce the size of inductance and capacitance and decrease the cost - The frequency modulation technology can simplify the EMI filter circuit
- X capacitor discharge function (LNK331x only)
Enhanced security and reliability features
- Soft start stress limits the starting system components
- Short circuit and open circuit fault cases automatic restart protection

- Input overvoltage protection (ovf)
- Sluggish over temperature protection (OTP)
- Extended drain the creepage distance between with other pins, improve the reliability of the application
- Integration of 725 v rated voltage MOSFET, has excellent resistance to surge performance
EcoSmart, high efficiency and energy saving
- Standby power supply IC when current < 100 (including A
- ON/OFF control mode can provide constant efficiency in a wide load range
- Easily meet all energy efficiency standards around the world
- The use of external bias load of time and space consumption < 30 mw
