IRIS4007K

Special Purpose Regulators Overview

The IRIS4007K is a smart power switch IC integrating a high-voltage MOSFET with PWM control for AC-DC and DC-DC switching power supplies. It operates within an input voltage range of 10V to 16V and provides a single output rated at 200V. The device supports both Quasi-Resonant (QR) and Pulse Ratio Control (PRC) modes, enabling zero-voltage switching to reduce high-frequency losses. Designed for through-hole mounting in TO-220AB packages, it functions reliably across temperatures from -20°C to 125°C.

Special Purpose Regulators Feature Summary

• Integrates high-voltage MOSFET and PWM controller for compact design
• Supports Quasi-Resonant mode for zero-voltage switching operation
• Includes internal overcurrent, overvoltage, and thermal shutdown protection

Special Purpose Regulators Applications

• High-frequency single-chip switching power supplies
• Flyback converter topologies
• Zero-voltage switching circuit designs

Special Purpose Regulators Procurement Notes
