Infineon Technologies REF_5BR4780BZ-1_15W1 Reference Board
Infineon Technologies REF_5BR4780BZ-1_15W1 Reference Board is a 15W auxiliary power supply reference design configured in a non-isolated flyback topology. The REF_5BR4780BZ-1_15W1 is based on the ICE5BR4780BZ-1, a product of Infineon’s CoolSET™ 5th Generation Fixed Frequency Plus family. An integrated 800V MOSFET in a DIP-7 package enables deployment to unstable grid environments and increases system robustness.

The emerging generation of home appliances, including air conditioners, are equipped with advanced features such as wireless control/monitoring capability, smart sensors, and touch-screen displays, transforming a static product into an interactive and intelligent home appliance capable of adapting to the smart-home theme. Infineon introduced the CoolSET 5th Generation Fixed-Frequency Plus ICE5BR4780BZ-1 switching controller to address this need efficiently and cost-effectively.
An auxiliary Switched-Mode Power Supply (SMPS) is needed to power the various modules and sensors, which typically operate from a stable DC voltage source. The CoolSET switching controller forms the system's heart, providing the necessary protection and AC-DC conversion from the mains to multiple regulated DC voltages to power the various blocks.
