TPS793285DBVR - PMIC - Voltage Regulators - Linear

The TPS793285DBVR is a programmable, triple linear voltage regulator, which is designed to deliver up to 3.3 A of output current. The device can operate as either 203 mV, 256 mV, or 314 mV fixed output voltage. The TPS793285DBVR is capable of high-density power conversion and provides good regulation accuracy and load transient response, as well as extensive features such as adjustable soft-start, output voltage tracking, and remote output voltage sensing.

The TPS793285DBVR offers a wide input voltage range of 5.5 V to 20 V and a switch-mode operation from 0.1 V to 12.6 V. The device also features an adjustable output voltage from 0. a V to 7.5 V. As a result, the device can perform PVT (power, voltage, and temperature)-based designs. An internal current-limit circuit monitors and limits in-rush current on the output.

Application Field

The TPS793285DBVR LDO provides three outputs that are used for 3 different applications. It is optimized for powering the digital logic, requiring relatively stabilized output voltages with minimal ripples. This makes it ideal to use in extension devices, such as digital cameras, digital video camcorders, digital audio recorders and terminal equipment like digital cellular phone batteries. The device can also be used in the automotive applications, such as 3.3 V to 12 V line brake and wide voltage MP3 players. It can also serve as an efficient power supply for microcontrollers and general purpose analog circuits.

Working Principle

At its heart, the TPS793285DBVR features an output voltage tracking and remote sensing circuit. This output tracking circuit is promised of low noise and fast response time. It eliminates the need for many external components and improves the efficiency of overall energy conversion. The device also features an internal current-limit circuit that helps monitor and limit in-rush current on the output.

In addition to the output tracking circuit, the TPS793285DBVR also features dynamic load-line regulation, which helps to maintain low output ripple. This is done by adjusting the output voltage depending on the load current. It also features shutdown logic, which is user programmable via an external digital control pin.

The TPS793285DBVR contains two low-dropout (LDO) regulators, one with an adjustable output voltage range of 0. a V to 7.5 V and a fixed-output voltage regulator with output voltages of 203 mV, 256 mV or 314 mV. The device operates from a single supply of 5.5 V to 20 V and can deliver up to 3.3 A of output current. Thermal protection is provided to ensure the device remains safe and reliable in extreme environments.

The TPS793285DBVR is built with an extensive feature set, making it ideal for high-density power applications such as digital cameras, digital video camcorders, digital audio recorders and automotive applications. It has a wide input voltage range, and can deliver up to 3.3 A of output current. Its precise output voltage regulation, fast response time, and dynamic load-line regulation capabilities ensure stable performance and reliability.
