THL 25-1211

DC DC Converters

DC-DC converters are electronic circuits that convert DC input voltage into DC output voltage and supply the load with constant voltage through a wide range of input voltage value. They are extensively used in various industrial, automotive and consumer applications. The THL 25-1211 is one such device that can dramatically improve the operational efficiency and performance of various applications.

The THL 25-1211 is a low-EMI, high-efficiency, single-output DC-DC converter designed to accept input ranges of up to 12V and provide up to 25W of power. It features on-board heatsinks to reduce thermal output and is designed to operate without additional cooling or forced-air cooling. When compared to linear regulators, the THL 25-1211 exhibits significantly less than 0.5% temperature coefficient.

This device is highly suitable for a wide range of applications such as standalone DC power systems or distributed power systems. Its compact size allows for easy integration into already existing systems that need to boost energy efficiency. The device features protection against overvoltage, over-temperature, and over-current protection, making it a safe and reliable power source for various types of applications. Additionally, the device has a power-good signal for user-specified voltage shut-down. The maximum efficiency of the device is over 90%, making it a great choice for applications that require optimized power consumption.

The THL 25-1211 works on a simple operating principle that makes it highly suitable for applications ranging from SMPS to critical UPS applications. When the input voltage is announced, the converter takes power from the input source, rectifies it by means of a bridge rectifier and filters it by passing it through an EMI filter. The current then passes through a high frequency DC to DC topology (either forward or flyback) with a PWM controller chip providing both output voltage regulation and current control. The device also features a power factor correction (PFC) stage to reduce the amount of ripple in the current and prevent interference with other electronic components.

The THL 25-1211 is a high-performance, cost-effective and reliable DC-DC converter that is designed to meet the requirements of a wide range of applications. It is capable of delivering up to 25W of power at 6-9V output voltage range, making it an ideal choice for various space-restricted applications. Moreover, its wide input voltage range, high efficiency and low-EMI features make it an excellent choice for both linear and non-linear applications.
