The Vcc range is 10 V to 30 V — the undervoltage lockout thresholds are set inside this band, so the bias rail must deliver at least 10 V before the controller starts switching. A 12 V or 15 V auxiliary winding is the typical source. This limits the TL3842BP to indoor, controlled-environment power supplies. An industrial or automotive design needing -40°C startup should look at the TL3842B IP grade variant. ## 8-DIP through-hole — legacy footprint, still socket-friendly Supplied in tubes — the standard DIP shipping format for manual or wave-solder assembly lines. ## Compliance and documentation ROHS3 compliant — no exemption-based paperwork needed for EU or UKCA markets. Texas Instruments provides the full compliance declaration and material disclosure on request.","metaTitle":"Texas Instruments TL3842BP PWM Controller","metaDescription":"Active-production PWM controller from TI.
