SL4053BN Datasheet The primary stroke starts some time before the actual valley at low ringing frequencies, and some time after the actual valley at high ringing frequencies. shows a typica curve for a reflected voltage N x Vo of 80 V. This voltage is the output voltage Vo (see ) transferred to the primary side of the transformer with the factor N (determined by the turns ratio of the transformer). shows that the system switches exactly at minimum drain voltage for ringing frequencies of 480 kHz, thus reducing the switch-on losses to a minimum. At 200 kHz, the next primary stroke is started at 33Ybefore the valley. The switch-on losses are still reduced significantly. SL4053BN Price

The 1800 series architecture is designed with emphasis on the total microcomputer system as an integral entity so that systems having maximum flexibility and minimum cost can be realized. The 1800 series CPU also provides a synchro- nous interface to memories and external controllers for l/0 devices, and minimizes the cost of interface controllers. Fur- ther, the l/0 interface is capable of supporting devices oper- ating in polled, interrupt driven, or direct memory access modes. |
