TPS51120RHBT is a switch-mode synchronous buck control IC, which is a DC-DC power converter integrated circuit, and is part of the PMIC (Power Management Integrated Circuit). It is part of the Voltage Regulators or DC DC Switching Controllers, and is designed for high power, high frequency applications such as servers and telecom equipment.
The TPS51120RHBT provides a complete synchronous buck solution to manage multiple power domains for a variety of computing, telecom and mobile applications. It has low component count, high efficiency and low thermal impact, with extended capability for high output current. It also delivers cycle-by-cycle current limiting, effective over-current protection, under-voltage protection, over-temperature protection, and soft-start to minimize inrush current.
The main component of the TPS51120RHBT is a low-power, high frequency regulator. It uses an ultra-low on resistance, high frequency synchronous power switch, allowing high speed switching and high efficiency. It also features a low loss current-sense amplifier, voltage reference and oscillator circuitry, along with the high frequency synchronous switch, which can be configured as either a boost or a buck converter. The integrated synchronous rectifier helps to minimize switching losses, allowing the converter to achieve full frequency operation at low duty cycles.
The working principle of the TPS51120RHBT is simple. It receives an input voltage, converts it to a regulated output voltage with the help of the synchronous transistor and the oscillator, and delivers it to the load circuit. It also uses the low-power, high frequency regulator to ensure continuous operation at the desired output voltage. The output voltage can be controlled by the voltage reference and the current-sense amplifier. The integrated over-current protection and over-temperature protection help ensure safe operation.
The TPS51120RHBT is designed for applications such as servers, telecom equipment, and mobile devices. It can provide high energy conversion efficiency and reliable power management solutions for complex high-current and high-power applications. The integrated synchronous rectifier helps to minimize switching losses, allowing the converter to achieve full frequency operation at low duty cycles. With its low component count, high efficiency and low thermal impact, the TPS51120RHBT is an ideal solution for high power, high frequency applications.
