SLVS038G is a control integrated circuit optimized for off-line and dc-to-dc converters, featuring low start-up current, automatic feed-forward compensation, pulse-by-pulse current limiting, etc.
The TL284x and TL384x series are current‑mode PWM controller integrated circuits designed for off‑line and DC‑to‑DC converter applications. They integrate features such as low start‑up current, undervoltage lockout, pulse‑by‑pulse current limiting, and a high‑current totem‑pole output suitable for driving N‑channel MOSFETs.
