9 / 35 page ![]() MV1001SC 8 3. Component selection procedure and calculation method The calculation is an estimate. In an actual circuit, errors may occur for various reasons, including the characteristics of individual parts and IC detection delays. Be sure to check with the actual apparatus and to make any adjustments needed. When using an oscilloscope to verify waveforms, note that the waveform and characteristics change depending on probe capacitance. In particular, pay close attention when measuring the Svin, Svout, and CS pins, and D-S of the MOSFET. Unless otherwise specified, the figures used in this document are typical values. 3.1 Basic circuit configuration Figure 4 shows the basic circuit configuration. Figure 5 shows the basic operation waveforms. Since MV1001SC can provide an internal power supply from the high-voltage start circuit in the Vin pin, a high pressure (less than DC250V) after full-wave rectification can be input directly (bus voltage direct supply). As shown in Figure 4, detecting the voltages on both ends of the choke eliminates the need for an auxiliary winding and enables a simple, low-cost circuit configuration.
