Description

UCC23525CDWYR is a Texas Instruments isolated flyback controller IC. It’s designed for offline and isolated power supplies, integrating a high‑voltage startup circuit, the controller logic, and a gate driver to drive a power MOSFET for a flyback converter. Key features typically include a wide input range, current‑mode control, programmable switching frequency, soft‑start, and protection functions (UVLO, OVP, OTP, short‑circuit/overtemp). The CDWYR suffix indicates the package and reel option used for manufacturing. Typical applications are AC adapters, telecom/industrial power supplies, and display/TV power supplies. For exact electrical specs and recommended external components, consult the TI datasheet on TI’s website.

Features

UCC23525CDWYR is a high‑voltage, off‑line flyback controller with primary‑side regulation. Key features include:
- Primary-side regulation (PSR): no optocoupler required for regulation in suitable designs.
- HV startup and operation: integrated high‑voltage circuitry for direct offline use.
- Peak‑current‑mode control with cycle‑by‑cycle current limit.
- Valley switching/flyback‑friendly operation for improved efficiency.
- Adjustable switching frequency via external components (wide range).
- Soft‑start to limit inrush and output overshoot.
- Protections: UVLO, overvoltage, overcurrent, and thermal shutdown.
- Enable input for easy control of operation and fault handling.
- Suitable for compact 8‑pin packages (DWYR variant).
Note: exact electrical specs (voltage ranges, frequency range, and protection behavior) depend on application and should be confirmed in the datasheet for your specific design.

Package

WSON-8 package (3×3 mm) with exposed pad; tape-and-reel packaging (YR).

Pinout

- Pin count: 16 pins (TSSOP-16 / SOIC-16 package, as indicated by CDWYR).
- Function: UCC23525CDWYR is a high-voltage primary-side flyback controller (often with an integrated HV MOSFET) for isolated offline SMPS. It provides PWM control, current-mode regulation, and protections (UVLO/OTP/overcurrent/OVP) for flyback power supplies.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- What kind of company: American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits, including power management, controllers, microcontrollers, and sensors.

Application

Typical application areas for UCC23525CDWYR include:
- Galvanically isolated interfaces in automotive and industrial networks
- Isolated CAN/CAN-FD transceivers
- Isolated gate drive/interface for power MOSFETs
- Isolated DC-DC converter control and power-supply front ends
- Motor drives and robotics
- Renewable-energy inverters, battery-management and smart-grid sensors
