NXP Semiconductors TEA2017DB1580 240W Demo Board
NXP Semiconductors TEA2017DB1580 240W Demo Board is a resonant power supply reference design based on the TEA2017AAT Digital Configurable LLC and Multimode PFC Controller, paired with the TEA2095T Dual LLC Resonant SR Controller. The TEA2017AAT can be configured to operate in DCM/QR, CCM fixed frequency, or multimode, which supports all operating modes to optimize the PFC efficiency. The TEA2095T incorporates an adaptive gate drive method to save the maximum amount of energy at any load. To increase efficiency, the TEA2095T can operate at 90μA with a -25mV regulation level, which optimizes functionality for use with low-ohmic MOSFETs.
The NXP Semiconductors TEA2017DB1580 240W Demo Board can operate at a mains input voltage between 90V (RMS) and 264V (RMS; universal mains). The Demo Board features three subcircuits:
- A DCM/QR/CCM-type PFC converter
- A resonant LLC-type HBC converter
- An SR resonant LLC-type output stage
The purpose of the Demo Board is to demonstrate the operation of the TEA2017 PFC + LLC controller and the TEA2025T Synchronous Rectifier in a single output voltage power supply, which includes the operation modes in a typical design. The performance passes general standards, including the EuP lot6 requirements.
The TEA2017DB1580 Demo Board can be connected to a PC using the RDK01DB1563 USB-I2C Programming Interface. The Ringo development software provides a graphical user interface (GUI) to set the TEA2017AAT Controller parameters.
