Decreased base spread resistance in these transistors also allows a wide driving range for simplified design of the horizontal deflection circuit
With the introduction today of its new BU45xx range of 1500 V horizontal deflection transistors, Philips Semiconductors has made it significantly easier for TV and monitor manufacturers to achieve these four important objectives, all of which depend on deflection circuit
Users designing piezo drive and deflection circuits
can use the performance options these ICs.
The high speed "A" devices are intended for high voltage, fast switching applications up to 100kHz such as induction heating, induction cooking, 480 to 575VAC offline inverters, flyback power supplies, UPS and microwave ovens, horizontal and vertical deflection circuits
