DC-DC converters provide a source of direct current DC power from a single source that is higher or lower than the desired DC voltage. THB 3-2422 is a good example of a DC-DC converter which is an isolated, bipolar, high-efficiency, step-down, power-factor corrected PFC PD converter that combines two power-factor correction, power-up protection PFC schemes and provides wide output range.

THB 3-2422 comes with many features such as:

• Wide input voltage range from 4V to 24V
• Power factor > 0.95
• Real output power up to 150W
• High efficiency up to 96%
• Maximum ambient temperature < 90°C
• Excellent output ripple and noise performance
• Small size and cost-effective

The working principle of THB 3-2422 is based on a buck converter. The first phase of this converter involves a voltage-based switch that reduces the power supply voltage for storing energy in an inductor. Once the energy has been stored, the second phase of the converter involves discharging the inductor to the output. THB 3-2422 is a synchronous buck converter, which means that the energy stored in the inductor is transferred to a transistor switch at the same time in each cycle. This type of synchronous buck converter offers the highest possible efficiency because switching losses are minimized and power losses are virtually eliminated.

The THB 3-2422 converter has several built-in features that help to make it an efficient power source. These features include:

• A built-in power-factor correction (PFC) system that improves power quality
• A current-mode control circuit for improved efficiency
• A variable-frequency oscillator for improved power stability
• An Optimized Magnetics design that minimizes power losses

The THB 3-2422 is designed for various applications including laptops, PCs, industrial automation, telecom equipment, and consumer electronics. It is capable of providing a wide range of outputs from 3V to 24V with up to 150 watts of power. With its high efficiency, low power losses, and built-in safety features, the THB 3-2422 is an ideal choice for power management applications.

In summary, the THB 3-2422 driver is a wide adjustable DC-DC converter with many features designed to make it an efficient and reliable power source. It offers a wide input voltage range from 4V to 24V with a power factor greater than 0.95. The built-in safety features and high efficiency make it ideal for a variety of applications.
