Description
The TIDA-00473 is a reference design of universal input, 10-W high efficiency, low cost power supply with three isolated outputs. This is a Constant-Voltage (CV) and Constant-Current (CC) flyback converter without Optical-Coupler and external MOSFET. The hardware is designed and tested to pass conducted emissions, surge, and EFT testing as per the EN55014 requirements for household appliances. This can be used in applications like cooker hoods and other appliances wherever motor drive along with user interface is involved.
Features
- Universal input voltage range to address customer needs across all regions
- Up to 700-V Start-Up and Smart Power Management Enables < 30-mW Standby Power
- Primary Side Regulation (PSR) control eliminates the optical-coupler
- Multiple operating modes and valley switching for optimum efficiency over entire operating range
- Valley Switching and Frequency Dithering to Ease EMI Compliance
- No need of external voltage compensation components
- Meets the requirements of Conducted Emissions standard – EN55022 class B
- Meets the requirements of EFT norm IEC6000-4-4 & Surge norm IEC61000-4-5
- Small Use PCB form factor (72 x 65 mm)
