TPS65265RHBR Application Field and Working Principle

PMIC (Power Management Integrated Circuit) technology is an integrated series of electronic components designed to provide, control and regulate power to electronic systems. Voltage Regulators, whose job is to convert voltage from one level to another, is an important part of PMIC. DC DC Switching Regulators are the most popular power supply design today. They are used in a variety of applications to increase or decrease the output voltage level. One of the most popular DC DC Switching Regulators is the TPS65265RHBR.

Applications of TPS65265RHBR

TPS65265RHBR, a single-loop synchronous buck converter, is a high efficiency and high current regulator in an ultra-compact 2.45mm x 2.45mm package. It is widely used in various industrial, automotive and consumer electronics applications, such as battery-powered handheld devices, server power supplies, IoT nodes, and industrial automation systems. Specifically, it is used to regulate the power in vehicles, medical systems, thin clients, gaming systems, and other devices which are reliant on power regulation.

Features of TPS65265RHBR

TPS65265RHBR is a high-performance and low-noise voltage regulator which can efficiently drive up to 10A continuous load current over the wide Vin and Vout range. It has a high integration of circuits and multiple protection mechanisms, including over current protection (OCP), over temperature protection (OTP) and UVLO (Under-Voltage Lockout). It also feature wide operating voltage range of input that is regulated by a one-time adjustable loop compensation component, making it easy to use in applications requiring output voltage of up to 26V continuously. With modern field-orientation control technology, the dynamic response of the power supply is optimized.

Working Principle of TPS65265RHBR

The working principle of the TPS65265RHBR is fairly simple. Its input power source is stepped up or stepped down to a desired voltage via a switching circuit, allowing for efficient and accurate power regulation. The electrical component of the switching regulator is made up of two parts: a transformer and a power switch. The power switch is turned on and off at a high frequency to generate the AC component required to step up or down the voltage. The undesired components generated in the process such as heat, is dissipated using heavy duty heatsinks.

The TPS65265RHBR also provides an external loop compensation component to adjust the AC component generated. The component is configured to create a feedback loop that responds to the input power changes and provides an adjustment to the output voltage accordingly. The feedback loop of this switching regulator allows it to more accurately and efficiently regulate power.
