DC–DC converters are indispensable building blocks in the electronics industry. Transformerless modules, such as the TMR 9-2410, offer improved efficiency over other converter series due to reduced winding losses and the elimination of opto–couplers or opto–isolators. With a high level of integration, these modules allow efficiency boosts in the design of regulated power supplies as well as in power management applications.

The TMR 9-2410 DC–DC converter is a step down unit, offering constant voltage and current conversion over a wide input voltage range of 9V to 24V DC. It has a 12V output voltage rating, which is adjustable via a potentiometer on the side of the module for fine tuning. The control circuit for the converter is one of the most important features of the module. By controlling the output voltage and current accurately, power loss is minimized and high efficiency achieved.

The TMR 9-2410 features a high switching frequency of up to 2MHz, allowing for a small form factor and the efficient use of energy. This makes the device ideal for compact and portable applications. Furthermore, the module supports a wide range of input voltage, from 4.5V to 30V, with wide temperature range of -40°C to +85°C. This enables the module to be used even in extreme or volatile conditions.

On the inside, the TMR 9-2410 utilizes a dual synchronous buck topology (2SB) to offer high efficiency and fast transient response. This topology requires two tiny integrated power switches, one for each output channel. The internal switches operate with fixed switching frequency, preventing instability and ensuring that the converter stays within its predetermined operational boundaries.

These two switched channels then separate the input voltage to deliver the desired output voltage or current. This is possible due to the PWM technology featured by the chip, which refers to the Pulse Width Modulation of the internal switches. The higher the frequency, the more precise is the voltage controlled circuit operation.

The switches make up a constant frequency DC–DC switch mode power supply. This type of converter is also known as switched-mode power supply (SMPS). During the ON time of one switch, the other switch will be OFF and so there is no voltage applied to the output, the output current also decreases. During the OFF period of one of the power switches, the other switch remains ON, and therefore the output current increases.

The two power switches are also responsible for providing the feedback loop to the inner voltage control circuit, ensuring a reliable output voltage. This feedback loop signals the controller about the current changes in the system and adjusts the output voltage accordingly. Thus a stabilized output voltage is achieved by controlling the secondary voltage with the use of error-amplifier.

Another characteristic of the TMR 9-2410 is its low ripple and noise measurement. This value is determined by a carefully designed filter circuit, which filters the current passing through the internal switch by adjusting its resistance and capacitance according to the current. This feature allows the converter to be operated correctly even in fluctuating environments.

The integration of the TMR 9-2410 DC–DC converter is relatively simple. The module also features overvoltage protection, undervoltage protection, and overcurrent protection, among other safety features. These safety features guarantee that the operation of the converter will be stable and reliable, even under a wide variety of conditions.

In conclusion, the TMR 9-2410 DC–DC converter offers improved efficiency along with outstanding features such as fast transient response, wide temperature range, low ripple and noise measurement, and excellent safety features. Its wide input voltage range and constant frequency switching structure make it an ideal choice for a variety of applications requiring highly regulated and stable output power.
