The PG-DSO-8 footprint is shared across Infineon's CoolSET controller family, so a board laid out for this part can take a pin-compatible integrated MOSFET variant if the power stage needs to be revised later. Tape & Reel or Cut Tape options match different production volumes. ## Lifecycle and sourcing Listed as Active with ROHS3 compliance. Sourced through independent distribution; availability and current pricing confirmed against an RFQ.","metaTitle":"Infineon ICE3AS03LJGXUMA1 Flyback Controller, 100kHz, 8-SOIC","metaDescription":"Infineon ICE3AS03LJGXUMA1 offline flyback PWM controller. 100kHz switching, 75% duty cycle, isolated output.
