FT838D2-BL-RT is a series of AC DC converters and offline switchers from Power Integrations. The product is a highly efficient, full-smoothed, half-bridge offline topology converter that delivers 16 watts of output power. It includes protection and control circuitry and is available in 5-pin DIP, TO-220, or TO-252 packages.The FT838D2-BL-RT is a bridgeless AC/DC converter that uses state-of-the-art half-bridge LLC (Link Switch-mode) topology. It is specifically designed for low cost and high efficiency, and is also designed to meet IEC61000-3-2 harmonic requirements. It has a wide input range of 85-264VAC, as well as integrate EMI filter and thermal shutdown protection circuitry.The FT838D2-BL-RT can be used in a wide variety of applications, such as LED lighting and small appliances. It provides a low-cost package for power applications as it includes the necessary protection and control circuitry, as well as integrated EMI filter and thermal shutdown protection. The wide input range allows the FT838D2-BL-RT to be used in multiple countries, with support for both 110V and 240V universal mains inputs.The FT838D2-BL-RT has two operating modes: continuous current mode and discontinuous current mode (DCM), and can efficiently deliver up to 16W of output power. It is also designed to provide optimal light load performance, with a 0.2W mode current at 230VAC/50Hz and a 0.8W mode current at 95VAC/50Hz. The product is designed with wide dimming range, and current dimming is also supported.The working principle of FT838D2-BL-RT is essentially the same as that of a conventional AC/DC converter. The input AC voltage is applied to the full bridge converter that rectifies it and the output is then converted to a regulated DC output voltage. The LLC topology used in the design ensures high efficiency during all operating conditions.The FT838D2-BL-RT also includes various protection features such as overload protection, short circuit protection, over temperature protection, and high peak current protection to ensure safe and reliable operation. The device is RoHS compliant and also includes safety approvals such as UL, CUL, TUV, CE and others.In conclusion, the FT838D2-BL-RT is an AC/DC converter that is designed specifically for low cost and high efficiency applications. The wide input range and the set of protection features ensure safe and reliable operation in multiple countries. The high efficiency, low operating temperature and wide range of dimming make the FT838D2-BL-RT an ideal choice for LED lighting and small appliances.
