Active production — what that means for your BOM
The TL3843P: It's a current-mode PWM controller that handles boost, flyback, and forward topologies, switching up to 500 kHz with a 97% max duty cycle.
Supply range and temperature — field-fit check
Through-hole 8-DIP package means you can socket it or solder it on a standard proto board — no hot-air station required, and orientation is obvious from the pin-1 notch.
ROHS3 compliant, so it passes the current EU material restrictions without an exemption hunt. Sourced to order through independent distribution — availability and current pricing confirmed at RFQ time. No stock-holding claim; quoted per your BOM quantity.
