UCC28910DR

The UCC28910DR is a high-performance, flyback switch-mode power supply controller developed by Texas Instruments. It's designed for use in isolated and non-isolated applications and is well-suited for off-line power supply solutions, such as adapters and chargers. The device integrates a 700V power MOSFET and operates in primary-side regulation (PSR) mode, eliminating the need for an optocoupler for feedback, thus reducing component count and cost.
Key features include constant-voltage (CV) and constant-current (CC) regulation, low standby power consumption, and comprehensive protection mechanisms such as over-voltage protection (OVP), over-current protection (OCP), and over-temperature protection (OTP). It uses a frequency jittering technique to minimize electromagnetic interference (EMI) and improves efficiency through a valley switching operation.
The UCC28910DR is available in an SOIC-7 package, making it suitable for compact power supply designs. Its integrated approach simplifies the design process and enhances the reliability of power supply solutions.

The UCC28910DR is an integrated power management controller from Texas Instruments designed for off-line flyback converters. It comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Here is a brief overview of its pin functions:
1. VDD (Pin 1): Power supply input for the controller. It requires a bias voltage to start and sustain operation.
2. GND (Pin 2): Ground reference for the device.
3. FB (Pin 3): Feedback input used for voltage regulation. It monitors the output voltage using an optical coupler.
4. CS (Pin 4): Current Sense input. It is used to detect the primary-side current for protection and control.
5. DRV (Pin 5): Drive output. This pin drives the gate of the external power MOSFET.
6. VDD (Pin 6): Connects internally in the package to Pin 1 (VDD).
7. NC (Pin 7): No connection; it's typically left unconnected or used for mechanical stability.
8. BP (Pin 8): A bypass pin that requires a capacitor to ground for internal bias.
The UCC28910DR is used primarily in applications requiring efficient power conversion with minimal external components, such as chargers and adapters.
