Description
UCC23511BDWYR is a Texas Instruments high‑voltage control IC used as the primary‑side/controller for isolated flyback switch‑mode power supplies. It is designed to drive an external MOSFET and regulate the transformer’s primary current in offline converters such as AC‑DC adapters, telecom power supplies, and LED drivers, often with minimal or no opto‑coupler feedback. The device typically includes a startup current source, gate‑drive logic, and protection features such as undervoltage, overcurrent/short‑circuit, and thermal protection, along with PWM control to set switching frequency. The BDWYR suffix denotes the specific TI packaging, temperature grade, and packaging options. For exact electrical specifications, pinout, protection details, and application notes, consult the TI product page and the UCC23511 datasheet.

Pinout
Pin count: 8 pins.
Function: The UCC23511BDWYR is a single‑channel isolated gate‑driver IC. It translates a logic input into a galvanically isolated gate drive for a power MOSFET/IGBT, providing an isolated VCC, gate output and return, input/logic side pins and protection features (e.g., UVLO, fast propagation and robust isolation barrier). It is used to drive power transistors in isolated power‑conversion and motor‑drive applications.
