The TPPM0115DR is a buck-boost DC-DC power module with integrated power MOSFETs. There are five versions of the module, which support input voltages from 4.5 V to 36 V. This module operates at a fixed voltage output, and the output voltage can be selected in the range of 1.8 V to 6 V. All modules are 1.2 A rated and have thermal shutdown, overvoltage protection, and external synchronization control.

The TPPM0115DR is a DC-DC switching controller, which is used to regulate the output voltage. This is done by controlling the duty cycle, which is set by an external resistor. The module supports an input voltage range of 4.5 V to 36 V, and the output voltage is adjustable in the range of 1.8 V to 6 V. The module utilizes an integrated power MOSFET, which helps to reduce the component count and improve efficiency.

The TPPM0115DR can be used in a variety of applications, such as industrial control, home and office appliance, automotive, and computer power supply. The module can be used to generate regulated 5 V output from an unregulated input. It is also suitable for battery-powered applications, where it can be used to maintain a stable output voltage despite fluctuations in the input voltage. The module is also capable of generating a low-voltage output from a higher input voltage, which makes it ideal for applications such as powering mobile devices.

In addition to regulating output voltage, the TPPM0115DR also offers additional features such as overvoltage protection and thermal shutdown. Overvoltage protection prevents the output from being damaged in the event of an excessive input voltage. Thermal shutdown shuts down the module when its temperature exceeds a specified limit. This is an important feature as it helps to ensure that the device will not overheat and cause damage.

The working principle of the TPPM0115DR module is based on the buck-boost switching scheme, which is commonly used in DC-DC power converters. This scheme consists of two switching components, which are controlled by a control circuit. The two switching components are the high-side and low-side MOSFETs, which alternately turn on and off.

When the high-side MOSFET is on, the input voltage is connected to the output capacitor. As the voltage on the output capacitor builds up, the high-side MOSFET is switched off and the low-side MOSFET is switched on. As the output voltage falls, the low-side MOSFET is switched off and the high-side MOSFET is switched on, resulting in a cycle. The duty cycle of the low-side and high-side MOSFET can be adjusted by an external resistor, which controls the output voltage.

The TPPM0115DR module is an efficient DC-DC switching controller, which is suitable for a variety of applications. It is capable of regulating output voltage, and also features protection functions such as overvoltage protection and thermal shutdown. It utilizes a buck-boost switching scheme to efficiently regulate the output voltage, which helps to keep power consumption low.
