TEA19161T/2Y

TEA19161T/2Y is a fully digital controller for high-efficiency resonant power supply. Together with the TEA19162T PFC controller and the TEA1995T dual SR controller, a complete resonant power supply can be built which is easy to design and has a very low component count. This power supply 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, any auxiliary low-power supply can be omitted. In contrast to traditional resonant topologies, the TEA19161T (LLC) shows 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. Typical applications include desktop and all-in-one PCs, LCD television, notebook adapter, printers.

• Integrated high-voltage start-up, integrated high-voltage level shifter (LS)
• Extremely fast start-up (< 500ms at Vmains = 100V (AC))
• Operating frequencies are outside the audible area at all operating modes
• Integrated soft start, power good function
• Maximum 500kHz half-bridge switching frequency
• Extremely high efficiency from low load to high load, adaptive non-overlap time
• Regulated low optocurrent, enabling low no-load power consumption
• Very low supply current during non-switching state in burst mode
• SO16 package
• Junction temperature range from -40 to +150°C
