Infineon Quasi Resonant 5-Channel 12-Pin Power Management IC DSO Package ICE2QR2280G1XUMA1

Infineon ICE2QR2280G1XUMA1 is a high-performance power management integrated circuit designed for switch-mode power supply (SMPS) applications. This quasi-resonant 5-channel IC is built on advanced 650V avalanche rugged CoolMOS™ technology combined with an integrated startup cell and quasi-resonant current mode flyback PWM controller. Packaged in a 12-pin DSO-16/12 surface mount package, the IC is compact and ideal for efficient power management in industrial and commercial electronics.

The device is rated to operate with a maximum input voltage of 800V and supports a maximum duty cycle of just 0.5%, allowing precise control of power delivery. It boasts a low under-voltage lockout threshold at 9.85V, facilitating easier optimization of system designs. The IC incorporates built-in digital soft-start functionality to reduce startup stress and active burst mode for achieving minimal standby power consumption, enhancing overall energy efficiency.

Infineon ICE2QR2280G1XUMA1 supports operation within a wide temperature range from -25°C to 130°C and meets RoHS compliance requirements for environmental standards. Additional integrated features include cycle-by-cycle current limitation with fold-back correction to ensure protection against overcurrent events, and digital frequency reduction with decreased load, aiding in noise reduction and EMI performance.
