At 37 W output, the part runs within its SOA for typical flyback designs. The 52 kHz switching rate balances efficiency and EMI. ## Active lifecycle — no LTB pressure The ICE2QR4780GXUMA2 carries an Active product status. No last-time-buy or end-of-life notices are on record. ROHS3 compliant. The PG-DSO-12-19 package is a standard Infineon footprint; reels store dry per MSL level (verify on the reel label). ## Fault protection set reduces BOM count Four built-in protection circuits — current limiting, overload, over-temperature, and over-voltage — eliminate external sense resistors and comparators in many designs. The 50% maximum duty cycle limits transformer flux swing, simplifying core selection. The 10.5 V to 25 V Vcc range accommodates standard bias windings. The 18 V start-up threshold ensures clean turn-on even with slow-rising input rails.","metaTitle":"ICE2QR4780GXUMA2 Infineon CoolSET Flyback, 800V, 52kHz, 37W","metaDescription":"ICE2QR4780GXUMA2 Infineon CoolMOS/CoolSET-Q1 offline flyback switcher, 800V breakdown, 52kHz, 37W, 16-SOIC.
