TPS563200DDCT is a step-down DC/DC power module that can deliver up to 3A of current output. It is a synchronous buck regulator integrated with a wide input voltage range of 2.10~5.5 V. It is suitable for a variety of applications, such as industrial and embedded computing, high-performance FPGAs and ASICs, servers, storage, and digital imaging.

The switching frequency of the TPS563200DDCT is adjustable from 100kHz to 500kHz depending on the current output requirements. It features programmable output voltage, precise external voltage reference, and an adjustable soft-start capability that eliminates overshoot current and its associated stress on the system. It also employs a wide-ranging adjustment of the switching frequency and the output voltage for improved system design flexibility.

The TPS563200DDCT has an over temperature protection scheme that senses a die temperature threshold, and shuts off the output power if that threshold is exceeded. It also has a short-circuit protection feature that protects both the output voltage and the internal circuitry from any shorted output devices.

The working principle of the TPS563200DDCT is based on a buck converter topology. The switching between the input voltage source and the internal circuits is regulated by a control element, like in all DC/DC regulators. Therefore, it employs an external resistor to set the output voltage. The switch element of the TPS563200DDCT is controlled by an internal high-performance constant frequency P-channel power MOSFET. This MOSFET switch is located just after the input voltage source and supplies energy to the inductor. The current then flows through the inductor, the output diode, and the output capacitor providing the DC supply at the output pins of the regulator.

The TPS563200DDCT is perfect for use in applications that require a high-efficiency DC/DC converter. Its wide input voltage range, adjustable soft-start, precise external voltage reference and adjustable switching frequency makes it ideal for industrial and embedded computing, FPGAs, ASICs, servers, storage, and digital imaging systems. Its over temperature protection feature prevents any unexpected losses while its wide-ranging adjustable switching frequency and output voltage offer improved system design flexibility.
