LYT5228D is a three-phase flyback offline AC/DC converter IC and it is mainly used in the power supply applications of consumer products and industrial related equipment. It is suitable for applications with input voltages in the range of 85Vac to 265Vac, at frequencies of 50hz or 60hz, and providing an output power of up to 10W.
The LYT5228D is an efficient and cost effective AC/DC power supply solution for medium and low power applications, providing simple and easy design flexibility to engineers for quickly realizing designs for various output power conditions, that are suitable for a range of applications like TVs, monitors, audio systems, and other consumer products.
The LYT5228D consists of an 800V rated MOSFET, a high speed current mode PWM CCM controller, a thermal shut-down circuit, and high voltage startup circuit. The 800V rating MOSFET provides high-efficient operation over all load, making it easy to design the power supply with high efficiency and small size. Besides, the high speed PWM control circuit achieves low harmonic distortion, low temperature rise, and high efficiency. The integrated high voltage start-up circuit requires an external detecting resistor, which is connected to the low voltage rail.
The main feature of the LYT5228D is its high efficient, simple construction, and small size which is achieved by using a high speed current mode PWM control IC and a low-side 800V output MOSFET. Additionally, it includes other useful features such as protection circuits, frequency synchronization between two or more ICs, and standby mode for energy saving. The IC supports frequency synchronization between two or more ICs and can optionally synchronized to a desired external clock up to 15kHz. Furthermore, the enabled Standby mode reduces the total power consumption to a minimum, thus ensuring high energy efficiency.
In a nutshell, the LYT5228D is an all-in-one AC/DC converter with integrated power MOSFET and high speed pulse width modulation controller, which allows designers to have a great time-to-market while having all the performance they need in power supply designs. It is suitable for applications with input voltages in the range of 85~265Vac, at frequencies of 50 or 60 hz, and providing an output power of up to 10W.
