The TPS56300PWPR is an advanced, low-cost, ultra-low-power, synchronous buck dc-to-dc converter. With an external inductor and capacitors, it is capable of regulating output voltages as low as 0.5V and up to its rated maximum of 5V at up to 8A depending on package and external components. The TPS56300PWPR incorporates a highly efficient lower-voltage (7V) switch, current-mode control, and a user-configurable logic-low enable. The device includes adaptive on-time control, a frequency compensation network, and programmable slew-rate control.

The TPS56300PWPR application field include portable devices, telecom/networking equipment, industrial control, embedded applications and consumer products. It is designed to minimize external components and minimize inductor size when reducing output voltage. The device also has the ability to operate in Multiple-phase mode, reducing the output ripple across the load. As a single stage power supply solution, the TPS56300PWPR enables up to 40% efficiency improvement compared to traditional two stage solutions while still providing fast transient response.

The working principle of TPS56300PWPR is based on the need to control the power regulation process in order to maintain output voltage. To do this, it utilizes two main components: a voltage regulator, and a switching circuit. The voltage regulator is responsible for maintaining steady output voltage by adjusting the width of the pulse when the input voltage changes, while the switching circuit is responsible for controlling the average power output by switching ON and OFF the power supply.

The TPS56300PWPR contains a very efficient and low-cost switch and current-mode control with adjustable turn-on/off time, further enhancing the efficiency and/or lowering output ripple. The turn-on slew-rate control can be adjusted to determine the maximum current that flows into the load. Additionally, the logic-low enable function allows the load to be disabled while the output voltage is still held at its programmed level.

The TPS56300PWPR is an advanced, low-cost, ultra-low-power, and synchronized buck voltage regulator designed to meet the exacting demands of today’s most sophisticated semiconductor designs. With its embedded low-cost switch and current-mode control, along with its adjustable turn-on/off time and programmable slew-rate control, it can deliver power conversion efficiency and accuracy with minimum external components and minimal inductor size.
