POWTECH PT4554D Non-isolated Buck-type LED Constant Current Driver Chip Datasheet
PT4554D is a non‑isolated buck‑type LED constant‑current driver chip designed for 85Vac‑265Vac input voltage range. The chip integrates a 500V power MOS, high‑voltage supply circuitry and current‑sampling circuit, allowing a very small bill of materials and high efficiency (up to 93%).
The device offers +/-3% current accuracy, excellent line and load regulation, and protection functions such as LED short‑circuit protection and over‑temperature current reduction. It is available in SOT33‑4, SOP‑7 and ESOP‑8 packages for various LED lighting applications. This manual is written in Chinese.
