TEA9026T/1规格书详情
General description
The TEA9026T is a digital LLC resonant mode controller for resonant power supplies
with a wide input voltage range. The power supply is easy to design and has a very low
component count. It meets the efficiency regulations of Energy Star, the Department of
Energy (DoE), the Eco-design directive of the European Union, the European Code of
Conduct, and other guidelines. So, no auxiliary low-power supply is required. To increase
the efficiency of a low-voltage supply output, the TEA2095T dual SR controller can be
added on the secondary side.
In contrast to traditional resonant topologies, the TEA9026T (LLC) achieves a high
efficiency at low loads due to the newly introduced low-power mode. This mode operates
in the power region between continuous switching (also called high-power mode) and
burst mode.
Because the TEA9026T is regulated via the primary capacitor voltage, it has accurate
information about the power delivered to the output. The measured output power defines
the mode of operation (burst mode, low-power mode, or high-power mode). With a single
configuration pin, the transition levels of the operating modes can be easily set.
The TEA9026T contains a low-voltage die with a fully digital controller for output power
control, start-up, initializations, and protections. These protections include overcurrent
protection (OCP), overvoltage protection (OVP), open-loop protection (OLP), and
capacitive mode regulation (CMR). The TEA9026T also contains a high-voltage siliconon-
insulator (SOI) controller for high-voltage start-up, integrated drivers, level shifter,
protections, and circuitry assuring zero-voltage switching.
The TEA9026T LLC controller enables the building of an easy to design, highly efficient,
and reliable power supply. The power supply can provide 90 W to 500 W output power
with a minimum of external components. It has a very low no-load input power (< 90 mW)
and a high efficiency from minimum to maximum load. So, no additional low-power
supply is required, which ensures a significant system cost saving and a highly simplified
power supply design, while meeting the latest power supply guidelines and regulations.
