AC DC converters are an important component of modern devices used to convert alternating current (AC) from the power supply into direct current (DC). This is necessary to power the circuits found in many electrical devices, such as PCs, televisions, gaming consoles, tablets, and more. The TB65S12C is an AC-DC converter module designed to meet the stringent requirements of consumer and industrial applications. In this article, we’ll explain the TB65S12C’s application fields and how it works.

The TB65S12C is a self-contained module that provides 12V DC output voltage levels from a normally available 85-265V AC input. It is compliant with international safety standards such as UL, CE, and IEC/EN 60950-1. Furthermore, the device has a built-in active PFC (Power Factor Correction) circuit which enables high efficiency over the entire input range. The module includes its own cooling fan and is able to supply up to 15A of output current and 95W of power. The TB65S12C also has comprehensive protection functions such as OVP (Over Voltage Protection), OCP (Over Current Protection), SCP (Short Circuit Protection), and OTP (Over Temperature Protection).

The TB65S12C offers multiple ways that designers can control the output voltage. The device includes a 5V logic compatible ON/OFF control pin with configurable output voltage (V ADJ connector), as well as a 0V-10V adjustable control pin (V OUT connector) for external potentiometer control. These features enable various system control options, such as remote systems, programmable containers, and so on. Additionally, the device includes 2 voltage sense outputs (V OT and V FR ) which provide indication of whether an overload or over voltage condition is present.

The TB65S12C utilizes a single stage flyback topology with an integrated primary side controller operating in critical conduction mode (CCM) and with a fixed frequency. The internal controller utilizes a valley switching technique to reduce the duty cycle at light load, thereby improving the efficiency of the converter. Once an overload is detected, the controller will reduce the maximum output current before the over current protection kicks in. The device uses a Green-mode function to reduce the no-load power consumption to less than 0.3W.

The TB65S12C is highly suitable for a variety of applications, including portable computers, office automation, automatic vending machines, industrial equipment, medical systems, and even industrial lighting. With its 95W output power, the device can easily power most medium-sized systems. Its high efficiency and built-in protection functions make it a great choice for powering modern devices that require a reliable DC power source.

In summary, the TB65S12C provides a reliable and efficient AC-DC power conversion solution for a wide range of consumer and industrial applications. With its high power output, comprehensive protection functions, and convenient control features, the TB65S12C is a great choice for powering modern electronics.
