Description
- MAXREFDES1034, Reference Design is an auxiliary power supply for TV applications. This design provides a 5V output and up to 5A of load current for system power of auxiliary functions such as monitoring and control. A wide operating range from 11.5V to 28V allows system designers to adapt this design to their input voltage needs. As with most modern TVs, flat panel screens limit the available area for the converter. This power supply is a low-profile design, which considers modern TV sizes and available space. This design focuses on providing high efficiency while limiting the total height to 6mm. This design is centered around the MAX17506 peak current- mode controller. The design is tested at 12V and 24V, which are common TV system voltages
