PFC Hybrid IC 22-Pin SIP

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.

• 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.
