With the continuous development and progress of electronic technology, TCM044PC2DC020B, also known as programmable DC/DC converter module, has become an indispensable part of electronic industry. It is widely used in many fields such as auto-control, instrumentation, automation, audio and video systems etc.TCM044PC2DC020B is a programmable DC/DC converter module with a wide input voltage range from 5-20V. It takes input voltage from any source within the specified range and then outputs high precision ±15V DC. The power output end is equipped with over-voltage, under-voltage and over-current protection functions. Moreover, its output voltage can be set according to the application requirements by just a few external parts.Working PrincipleThe TCM044PC2DC020B adopts the insulated voltage regulation technology. It uses discrete pulse width modulation (PWM) to turn the voltage. It consists of two parts, the first part is the voltage-transformer circuit and the second part is the voltage regulator control circuit. The high voltage is divided by a step-down transformer circuit to low voltage, and then fed into the voltage regulator circuit to adjust the voltage stability and output the required DC voltage.The voltage regulator control circuit comprises the pulse-width modulator, feedback comparing circuit and error amplifier circuit. The pulse-width modulation section converts the input signals into a series of pulses which delivers output voltage with high stability and accuracy. The comparing part compares the programmable voltage with the output voltage and then sends the signal to the voltage regulator circuit to correct the output voltage, realizing the division of output voltage.Application FieldTCM044PC2DC020B is widely used in different fields. In automotive control systems, it is used to regulate the 12V automotive power supply into 5V, 15V, 33V etc. for various sensors and receivers; in instrumentation, it is used to convert the AC waveform into smooth transistor signal; in audio and video systems, it can provide clean power for various communication devices; in surveillance equipment, it is used to stabilize the sensitivity of CCD and provide stability for power supply; in laboratory, it is used to provide power for precision instruments.ConclusionThe TCM044PC2DC020B programmable DC/DC converter module is a high-precision module with wide input voltage range and great output accuracy. It is widely used in automotive control, audio and video systems, instrumentation, surveillance equipment and laboratory. It provides clean and stable power supply for different devices. This module adopts the insulated voltage regulation technology to realize the output voltage setting according to the application needs. It is an ideal and reliable power supply module for the current electronic industry.
