Ordering number : EN*A1052 Thick-Film Hybrid IC STK760-221A-E Single-phase Rectification PFC Hybrid IC Overview The STK760-221A-E is an average current control type hybrid IC that integrates in a single package the power stages for the step-up active converter and the control IC, and overcurrent/overvoltage protection circuits. It is designed to improve the power factor of single-phase AC power supplies. Applications • Power rectification for air conditioners and general-purpose inverters as a single-phase rectification active converter. Features • IGBT switching power device employed in the active converter output stage. • On-chip regulator for PFC control supports a wide range of input voltage (up to 50V). • Full complement of protection circuits, including overcurrent, overvoltage, and undervoltage protection, plus soft start function. • Logic level PFC controlled ON/OFF control. • On-chip light-load correction circuit that minimizes output voltage increase when no load is applied. • SIP package providing a high degree freedom for mounting the IC in the set.

If the VIN (DC) input is applied to the IC at the timing shown in Figure 12 or 13, however, since the soft start circuit is inactive in this case, it is likely that the overcurrent protection circuit is activated and audible tone is generated out of the coil. To avoid this area of timing, it is necessary that the ON/OFF or VCC input be applied after VIN (DC).
