TMV 1212DEN

DC DC Converters

The TMV 1212DEN is a type of DCDC converter. It is comprised of two major sub-systems - the controller and the switcher - and is suitable for driving low-power DC motors from a voltage supply. It is commonly used in a multitude of applications including robotics and automotive systems.

Controller

The controller of the TMV 1212DEN is capable of performing closed loop speed control from a remote analog or digital signal. It has a maximum operating voltage of 12V and a current rating of 4A. The controller enables the switcher to obtain the desired current that drives the motor. It can operate over a wide frequency range, and its intelligent design allows for efficient and reliable operation.

Switcher

The switcher is composed of two N-channel power MOSFETs and can support a wide range of operation frequencies, from 5kHz to 30kHz. By properly tuning the switcher, the TMV 1212DEN can accurately achieve the desired speed of the motor. Furthermore, the operation frequency range of the switcher is adjustable, allowing for flexibility in the control of motor speed.

Working Principle

The TMV 1212DEN works on the principle of pulse-width modulation (PWM) control. The controller receives input signals from a remote analog or digital source and then controls the switcher accordingly. When the switcher is turned on, the motor is driven by the positive voltage. During each switching cycle, the analog or digital signals control the width of the pulses applied to the motor for precise speed control. Although the system voltage is low, the TMV 1212DEN provides a high-power efficiency due to the pulsed output.

Application Field

The TMV 1212DEN is widely used in a number of different applications. These include robotics, smart home systems, HVAC systems, medical equipment, and automotive systems. The power-efficient design and the wide frequency range make the TMV 1212DEN suitable for a variety of applications.

Conclusion

The TMV 1212DEN is a DC-DC converter that includes a controller and switcher. Its controller enables the switcher to achieve the desired current needed to drive the motor. The working principle of the TMV 1212DEN works on the principle of PWM control, with the analog or digital signal controlling the pulse width for precise speed control. Furthermore, its wide range of applications, from robotics to automotive systems, makes the TMV 1212DEN the perfect choice for low-power DC motor control.
