TPS77028DBVT is an adjustable linear regulator PMIC (Power Management IC) that provides an accurate output voltage between 0.8V and 5.5V over a 2.5V to 5.5V input voltage range with a maximum load current of 1A. The device is designed with protection features such as thermal shutdown, output short and over current protection. Ideal applications are set-top-boxes, media players, game consoles, digital TVs, and other audio and video systems.

TPS77028DBVT is capable of providing a regulated output voltage with up to 1A of current from a 2.5V-5.5V input voltage. It offers embedded protections such as over-current protection, thermal shutdown and output short-circuit protection. It also features a logic-controlled enable, reset and power management functions. To control the output voltage of the device a single external resistor is used for setting the output voltage. The device also uses low-noise LDO (Low Drop Out) technology which minimizes loss of power in the output stage.

Working Principle

The TPS77028DBVT is an adjustable linear regulator that can be configured to provide a precise and stable output voltage. The device consists of a voltage reference, an error amplifier, a PWM controller and a configurable outputs switches. The internal voltage reference provides the reference voltage. The error amplifier is used to compare this reference voltage with the output voltage. The PWM controller controls the output voltage by switching the outputs on and off as needed. The output switch is a low on-resistance switch which can be used to cut off the power when the device is in shutdown. The output voltage is set by an external resistor divider connected to the ADJ pin.

Application Field

TPS77028DBVT is suitable for many applications such as automotive, consumer electronics, and industrial systems. The device is used in systems that require an adjustable output voltage. It is also well-suited for applications that require low ripple, high current and thermal shutdown protection. Applications include set-top-boxes, media players, game consoles, digital TVs, and other audio and video systems. The device also offers very low power consumption, enabling power savings in many applications. It can be used to provide power to an embedded or mobile systems, or to provide the supply voltage to an audio or video system.
