TEA19161T/2Y Typical application Circuitry

TEA19161T 2Y

TEA19161T/2Y is a voltage-mode pulse-width modulation (PWM) controller IC designed for offline flyback converters, mainly used in power supply applications. Below, you'll find its key features, an example application scenario, and considerations for designing a circuit using this PWM controller.

Key Features of TEA19161T/2Y:

1. Voltage-Mode PWM Controller: TEA19161T/2Y is designed as a voltage-mode PWM controller, suitable for various power supply topologies.

2. GreenChip Technology: It often incorporates NXP's GreenChip technology for high energy efficiency and reduced standby power consumption.

3. Soft Start: The IC may have a soft-start function to prevent excessive inrush current during power-up.

4. Over-Temperature Protection: It includes over-temperature protection to safeguard against thermal issues.

5. Frequency Jitter: Some versions may offer frequency jittering for lower electromagnetic interference (EMI).

Example Application: Offline Flyback Power Supply

Let's consider designing a simple offline flyback power supply circuit using the TEA19161T/2Y PWM controller.

Circuit Connection:

1. TEA19161T/2Y PWM Controller:

- Pin 1 (VDD): Connect this pin to the positive supply voltage (e.g., +12V).

- Pin 2 (FB): Connect this pin to the feedback voltage divider network to set the output voltage.

- Pin 3 (GND): Connect this pin to the ground reference.

- Pin 4 (CS): Connect this pin to a current sense resistor for current limiting.

- Pin 5 (DRV): Connect this pin to the gate driver of the power MOSFET.

- Pin 6 (D): Connect this pin to the drain of the power MOSFET and the primary winding of the transformer.

- Pin 7 (S): Connect this pin to the source of the power MOSFET.

- Pin 8 (RT/CT): Connect this pin to an external resistor and capacitor to set the switching frequency.

Design Considerations:

1. Feedback Network: Design the feedback voltage divider network to set the desired output voltage.

2. Current Limiting: Size the current sense resistor appropriately for desired current limiting.

3. Transformer: Choose an appropriate transformer with the required turns ratio for voltage conversion.

4. External Components: Select external components, such as the output diode, input capacitor, and output capacitor, according to the application's requirements.

5. Protection: Implement necessary protection mechanisms like over-temperature and over-current protection.

6. EMI Filtering: Include EMI filtering components to minimize electromagnetic interference.

7. Layout: Pay attention to the PCB layout for proper grounding and noise reduction.

8. Efficiency: Optimize the design for efficiency, especially if it's intended for low-power or energy-efficient applications.

In conclusion, the TEA19161T/2Y PWM controller is suitable for designing offline flyback power supplies. When using this IC, consider feedback, current limiting, transformer selection, external components, protection, EMI filtering, layout, and efficiency to create a reliable and efficient power supply circuit.
