Notes:  
1. Typical output current in a non-isolated buck converter with devices operating  
at default current limit and adequate heat sinking. Output power capability  
depends on respective output voltage and thermal requirements. See Key  
Applications Considerations Section for complete description of assumptions,  
including fully discontinuous conduction mode (DCM) operation.  
2. Mostly discontinuous conduction mode.  
Description  
The LinkSwitch™-TN2 family of ICs for non-isolated off-line power  
supplies provide dramatically improved performance compared to  
traditional linear or cap-dropper solutions. Designs using the highly  
integrated LinkSwitch-TN2 ICs are more flexible and feature increased  
efficiency, comprehensive system level protection and higher reliability.  
The device family supports buck, buck-boost and flyback converter  
topologies. Each device incorporates a 725 V power MOSFET, oscillator,  
On/Off control for highest efficiency at light load, a high-voltage  
switched current source for self-biasing, frequency jittering, fast  
(cycle-by-cycle) current limit, hysteretic thermal shutdown, and output  
and input overvoltage protection circuitry onto a monolithic IC.  
3. Continuous conduction mode.  
4. Packages: P: PDIP-8C, G: SMD-8C, D: SO-8C.  
BYPASS pin capacitor value. The high current limit level provides  
maximum continuous output current while the low level permits using  
very low cost and small surface mount inductors. A full suite of  
protection features enable safe and reliable power supplies protecting  
the device and the system against input and output overvoltage faults,  
device over-temperature faults, lost regulation, and power supply output  
overload or short-circuit faults.  
LinkSwitch-TN2 ICs consume very little current in standby resulting in  
power supply designs that meet all no-load and standby specifications  
worldwide. MOSFET current limit modes can be selected through the  
The device family is available in three different packages: PDIP-8C,  
SO-8C, and SMD-8C.
