Introduction

The Texas Instruments TPS40200DRBR is a voltage regulator designed to be used with other devices in order to provide adequate power and regulation when connected to a DC source or battery. It works by using two integrated AC switches and a single Stage PFC controller to regulate voltage across a range of input voltages.

Application Field

The TPS40200DRBR is capable of providing a wide variety of voltage outputs and is suitable for use in many DC-DC applications from low-to-high-power. These applications may include SMPS, AC/DC converters, UPS, Power Factor Correction systems, and switching regulators in applications that require the highest efficiency and wide input voltage ranges.

Working Principle

The TPS40200DRBR is a digitally controlled and synchronized switching regulator. It uses two integrated AC switches and a single-stage PFC controller to regulate and switch voltage across a range of input voltages. The IC includes high-side and low-side MOSFETs, as well as a current sensing circuit and voltage control loops. The TPS40200DRBR uses a voltage-mode control technique that is designed to provide good output voltage regulation and transient response. The two MOSFETs are controlled using internal logic signals, which are generated from the logical blocks inside the IC. The switching frequency and period can be configured according to the application requirements. The IC features short-circuit and over-temperature protection. It is equipped with an adjustable under-voltage lockout feature and the ability to adjust output voltage and current limits. In order to ensure reliable and efficient operation, a frequency limit and a slope compensation feature are also included.
