FAQs
What is FSD210B?
The FSD210B is a Green Mode Fairchild Power Switch (FPS) integrated circuit designed for use in power supply applications. It is specifically tailored for off-line power supplies in consumer electronics, offline adapters, and auxiliary power supplies. The device integrates a Pulse Width Modulation (PWM) controller with a high voltage power MOSFET, making it suitable for low power AC/DC supplies.
How Does FSD210B Work?
The FSD210B operates by integrating a PWM controller and a power MOSFET into a single device, enabling efficient power supply operation. The device includes features such as over-temperature protection, over-load protection, and auto-restart for enhanced safety and reliability. It regulates the power supply output based on the feedback from the secondary side of the transformer, providing stable and well-regulated power to the load.
How Many Pins does FSD210B have and What are the Functions of the Pinout Configuration?
The FSD210B is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- FB: Feedback pin for connecting the secondary side feedback circuitry.
- GND: Ground pin for the device.
- VDD: Supply voltage pin for the device.
- UVLO: Under Voltage Lock Out pin for protection against low supply voltage.
- DRV: Gate driver output pin for the internal power MOSFET.
- BP/M: Brownout protection and soft-start pin.
- VCC: Output voltage to the primary side of the transformer.
- SS/CLK: Soft-start and frequency setting pin for the device.
What are the Pros and Cons of FSD210B?
Pros:
- Integration: Combines PWM controller and power MOSFET in a single package, reducing external component count.
- Green Mode Operation: Provides high efficiency and low standby power, contributing to energy savings and environmental friendliness.
- Protection Features: Includes over-temperature and over-load protection for enhanced safety and reliability.
- Compact Package: Housed in an 8-pin SOIC package, suitable for space-constrained designs.
Cons:
- Operating Frequency Limitation: May not be suitable for high-frequency switching power supply applications.
- Design Complexity: Requires careful consideration of transformer design and feedback loop for optimal performance.
Are There Any Equivalents/Alternatives to FSD210B for Recommendation?
The FSDL0165RN from Fairchild Semiconductor is an equivalent part to the FSD210B, offering similar functionality for power supply applications. Alternatives to the FSD210B include the STR-A6000 series from Allegro MicroSystems and the IR2153 from Infineon Technologies.
