The TPS2065DBVT is a versatile power distribution switch, load driver, and linear regulator. This device combines a single low-side switch with a buck regulator and a driver-level power switch, providing two separate regulated output voltages for integrated or isolated applications. The TPS2065DBVT is designed for mobile power-delivery applications, particularly for battery-powered applications where a single- or split-supply configuration is desired.

The TPS2065DBVT switch combines a high-side PMOS switch, a low-side NMOS switch, a flexible buck regulator, and a driver that can be used to control sort of independent linear regulator outputs. The popular device is typically used to provide efficient power distribution and hot-swap protection in battery-powered applications. Its integrated reverse-battery protection and hot-swap capabilities make it ideal for a variety of applications.

The TPS2065DBVT is a fully-integrated power-management integrated circuit (PMIC) that provides an efficient, low-cost, low-power alternative to discrete designs. The device provides two regulated output voltages from one input supply, eliminating the need for two separate supplies. The TPS2065DBVT has two voltage-regulated switch outputs with driver-level logic control. The pre-driver stage supports logic-level and hot-swap control with a low power consumption.

The device also provides integrated protection circuitry to protect the output voltage from short-circuit and reverse-battery damage. The hot-swap control protects the system in the event of an unexpected short to ground. A single shutdown line can be used to place both of the switches off-line when necessary. With its wide operating temperature range, the TPS2065DBVT can be used in a variety of power-distribution applications.

The TPS2065DBVT is based on a proprietary switching architecture that allows both constant switching frequency and pulse frequency modulation to optimize power efficiency, reduce noise, and minimize system cost. The device combines a fixed-frequency buck regulator with a driver stage to control an independent linear regulator output voltage. This architecture enables the TPS2065DBVT to provide efficient power management, even when supplying lower output currents with a wide input supply range.

The TPS2065DBVT integrates several features that simplify power distribution and minimize component count. It provides a total shutdown mode, reverse-battery protection, hot-swap protection, and an adjustable over-current protection circuit. The device is also equipped with a single compensation pin that can be used to set the loop compensation for both the buck regulator and the linear regulator output.

The TPS2065DBVT is an ideal choice for mobile power-delivery applications that require two separate regulated output voltages. The device combines a high-side and a low-side switch with an efficiently tuned buck regulator and driver stages to provide a high performance and cost-effective solution for power-supply distribution. With its wide operating temperature range, reverse-battery protection, over-current protection, and hot-swap capabilities, the TPS2065DBVT is the perfect choice for distributed power applications.
