LYT2002D-TL, is a high-end isolated DC-DC module under LYT-DC series products. It is a closed-loop isolated DC-DC converter integrated with monolithic IC and can provide up to 11.44W output power over an input voltage range of 9 to 36VDC and 19 to 75VDC. The module is applicable in telecom and industrial systems, providing high isolation, power density and excellent power consistency.

LYT2002D-TL is categorized under PMIC - AC DC Converters and Offline Switchers. It is primarily used for Telecom, Industrial and Automotive applications and works on a switched-mode power supply (SMPS) principle. The SMPS is the most cost effective and efficient power supply that relates directly to the input voltage and the output current. When the voltage and current need to be changed, the power supply is automatically switched on or off to maintain the output voltage. In other words, the switching is done by controlling the on/off states of the power supply, thus solving the problem of changing voltage and current. The switching is done automatically, without the need for user intervention, making it highly reliable.

LYT2002D-TL has a wide range of features and benefits like low component count, high efficiency, improved thermal performance, soft start, power good, and single stage topology. The module incorporates a unique high performance pulse width modulated (PWM) IC. This cost effective and highly efficient IC, has multiple clock frequencies for maximum efficiency and control. It also features built in induction suppression, high voltage isolation and current limit circuits for improved reliability and system availability. With its wide input range, the module can be configured to accept both AC and DC power and generate an output voltage up to 400V, which makes it ideal for industrial equipment. Additionally, the module has an internal temperature sensor, short circuit protection and overcurrent detection feature, which makes it safe and easy to install.

The working of the module is based on two main components, the control IC and the power transformer. The Control IC consists of a low power resistor, a comparator, a voltage multiplier and a voltage regulator. The controller compares the input voltage with the output voltage and generates a pulse width modulated (PWM) signal. This signal is then amplified by the voltage multiplier and the output voltage is regulated by the voltage regulator. The PWM signal is then fed to the power transformer, which converts the input voltage to the required output voltage. The power transformer consists of an inductor, a power switch and a rectifier. The power switch is connected to the output of the voltage regulator and is responsible for the actual switching. When the power switch is turned on, the current through the inductor increases, increasing the output voltage. The rectifier takes the output of the power switch and converts it into the required output voltage.

The advantages of LYT2002D-TL include improved efficiency and low standby power consumption. The module is widely used in industrial and automotive applications, providing reliable performance. Additionally, the module has high voltage isolation, making it suitable for use in numerous applications like switch mode power supplies, motor control centers, multi-output power supplies and power related electronic circuits. Furthermore, its wide input range, and multiple clock frequencies provides efficient control and helps in reducing the component count and cost. Lastly, the module has optimized design, ease-to-use, excellent power consistency, efficient thermal management and improved reliability providing optimal performance.
