(1) I/O specification and transformer Control IC MS1003SH Input specification AC85–132V Output specification 12V/2.1A Transformer ECO2219 (made by TDK) (2) Initial design value list VDC(min) 102 [V] D 0.47 Cq 470 pF VDC(max) 187 [V] Po 25.2 [W] PL Po 1.2 [W] f(min) 50 [kHz] 0.85 Ae 46.4 [mm 2] VO1 12 [V] VNC 15 [V] B 300 mT Vo1 rectification diode forward voltage: VF1 0.8 [V] VNC rectification diode forward voltage: VFNC 0.6 [V] High signal: Normal Mode Low signal: SP Stby Mode Super standby mode switching circuit This circuit is based on the results of calculations described in Section 6.2 below. Actual values may differ from calculations due to differences in efficiency and in the response system, variance in IC thresholds, temperature drifts for each component, and various other factors. Use the results of calculations as guidelines. In the example circuit, the OCL resistance (R(OCL)) is changed from 0.37 Ω to 0.39 Ω due to discrepancies between the actual device and calculations. The transformer inductance at AL-value = 140 has been changed from 0.656 mH to 0.647 mH based on information from the transformer manufacturer. |
