TPS54380PWP is a complete, synchronous 2-phase, 2.25 V to 5.5 V step-down DC/DC switching regulator which offers superior efficiency, superior transient performance and superior power density. It supports up to 18 A load current from a tiny, low profile 8-pin WSON package and provides high efficiency, precise output voltage and high power density. The device integrates a high-side N-channel MOSFET, two low-side N-channel MOSFETs and current limit resistor for controlling the current.}

TPS54380PWP is suitable for a wide applications. Some examples are IEEE 802.3at LAN and Ethernet powered devices, 1U height blade servers, medical, automotive, LED lighting and microprocessors.

The working principle of TPS54380PWP is based on Pulse Width Modulation (PWM) control scheme. Basically, the circuit uses a switching element (MOSFET) to produces a square wave input to the inductor. When the switch is closed, inductor current is charged up and energy is stored in its magnetic field. When the switch is open, this stored energy is transferred to the output capacitor and the output voltage is regulated. The duty cycle of the switching element is varied by the feedback circuit to regulate the output voltage.

In summary, TPS54380PWP is suitable for applications that utilize high efficiency, precise output voltage and high power density DC/DC switching regulators. The device is capable to deliver up to 18 A load current from a tiny, low profile 8-pin WSON package. It uses a PWM control scheme to regulate the output voltage and the duty cycle of the switching element is varied by the feedback circuit.
