TPS60402DBVT belongs to a family of DC DC switching regulators, which are widely used in communication and industrial applications. The TPS60402DBVT is a low noise, highly efficient, half-brick (58mm × 22mm) DC/DC converter with integrated inductor, output diode, and power components. The isolated buck regulator operates from an input voltage of 8.0 V to 14 V, and it is designed to operate at a switching frequency of 1.2 MHz. The device offers two selectable output voltage a nominal value of 3.3 V and an adjustable output voltage from 0.6 V to 3.2 V. The TPS60402DBVT features differential remote sense and fixed output voltage, with a built-in soft-start capability and power good signal, as well as thermal and short-circuit protection for added safety.

The working principle of TPS60402DBVT is based on the switching of DC voltage from the input supply source. The switching regulator is composed of two main components: a power switch (MOSFET or transistor) and an inductor. At the beginning of a cycle, the power switch is ON and energy is stored on the inductor, which increases the current of the inductor. Then, the switch is turned OFF and the stored energy is released from the inductor, thus reducing the inductor current and providing the required output voltage. The switching frequency is determined by the control chip, and the output voltage is stabilized by a feedback error amplifier.

The TPS60402DBVT due to its high efficiency, low noise and small size, can be used in many applications. It is well adapted for applications in communication systems such as base stations, backhaul radios, 802.11 a–b–g radios, DSL access concentrators and test equipment. Furthermore, this device can also be used in industrial applications like dc motors, temperature and printing equipment, UPS systems, photovoltaic systems, metering equipment and industrial controls.

Overall, the TPS60402DBVT is an excellent choice for low power applications requiring high efficiency and low noise. Its high efficiency reduces losses and ensures for a long life and reduced energy costs, making it well suited for any application in communication systems and industrial controls where efficiency and size are important.
