TPPM0115D

PMIC - Voltage Regulators - DC DC Switching Controllers

The TPPM0115D is an adjustable, isolated, wide input range, high-efficiency DC programming current DC-to-DC buck-boost converter power supply module. It can provide up to 1.5A of output current for a maximum input voltage of 26V. It is suitable for applications where a regulated power supply is needed that allows the user to program the output voltage over a wide range.

Application Field

The TPPM0115D can be used in a variety of applications including LED lighting, motor speed control, industrial automation, communications systems, RF power amplifiers, industrial control, robotics, automotive systems, medical equipment and consumer electronics. It is suitable for applications where a wide range of input and output voltages are required, as it can be programmed to generate either a constant voltage or constant current output.

Working Principle

The TPPM0115D employs a buck-boost converter topology to produce an output voltage independent of the input voltage. The device consists of two power transistors, an inductor, and two capacitors. As the input voltage changes, the transistors alternately switch on and off to control the output voltage according to the control voltage provided. When the output voltage is lower than the input voltage, the device acts as a buck converter, converting the input voltage to a lower output voltage. When the output voltage is higher than the input voltage, the device acts as a boost converter, raising the input voltage to a higher output voltage.

The TPPM0115D includes a voltage feedback loop allowing the user to program the output voltage between 0.8V and 25V. The output voltage is controlled by a current-mode control loop, which adjusts the output current to maintain a constant output voltage. By adjusting the reference voltage, the output voltage can be easily programmed over a wide range. The current-mode control eliminates the need for external components such as resistors or capacitors and allows for stable operation over a wide temperature range.

Conclusion

The TPPM0115D is an adjustable, isolated, wide input range, high-efficiency DC programming current DC-to-DC buck-boost converter power supply module. It is suitable for applications where a regulated power supply is needed that allows the user to program the output voltage over a wide range, such as LEDs, motor speed controls, industrial automation, and communications systems. It employs a buck-boost converter topology to produce an output voltage independent of the input voltage and includes a current-mode control loop to maintain a constant output voltage. With its wide input and output voltage range, high-efficiency, and adjustable programming, the TPPM0115D is an ideal solution for many applications.
