... In addition, there is a 6.4 V shunt regulator clamping the BYPASS/MULTI-FUNCTION pin at 6.4 V when current is provided to the BYPASS/MULTI-FUNCTION pin through an external resistor. This facilitates powering of TinySwitch-PK externally through a bias winding as required for TNY377-380. Powering the TinySwitch-PK externally in this way also 5 decreases the no-load consumption to below 60 mW. TNY375-380 3 Rev. A 05/07 ...

TNY375-380 BYPASS/MULTI-FUNCTION Pin Undervoltage The BYPASS/MULTI-FUNCTION pin undervoltage circuitry disables the power MOSFET when the BYPASS/MULTI- FUNCTION pin voltage drops below 4 steady state operation. Once the BYPASS/MULTI-FUNCTION pin voltage drops below 4 steady state operation, it must rise back to 5. enable (turn-on) the power MOSFET. ...

... The external resistor (4 MW) is connected to the EN/UV pin in this case to prevent unwanted restarts. www.powerint.com TNY375-380 With the TNY375 and TNY376, no bias winding is needed to provide power to the chip because it draws the power directly from the DRAIN pin (see Functional Description above). This eliminates the cost of a bias winding and associated components ...

... TNY375-380 should be located as close as possible to the SOURCE and BYPASS pins of the device. For best performance of the OVP function recommended that a relatively high bias winding voltage is used, in the range of 15 V-30 V. This minimizes the error voltage on the bias winding due to leakage inductance and also ensures adequate voltage during no-load operation from which to supply the IC device consumption ...

... TNY375-380 NOTES: A. For all BP/M pin capacitor values accurate estimate of device controller current consumption at no-load, since operating frequency is so low under these S1 conditions. Total device consumption at no-load is the sum Since the output MOSFET is switching difficult to isolate the switching current from the supply current at the DRAIN. An alternative is to measure the BP/M pin current at 6 ...
