The TPS78236DRVR is a dual-channel voltage regulator designed for high performance and energy efficient applications. It combines a buck-boost converter with two channels of wide output-range linear regulators. The device supports a wide input voltage range of 3.0 V to 28 V, and its two buck-boost converters can offer up to 8 A of output current. The two linear regulators are fully programmable from 0 V to 4.20 V and can deliver up to 500 mA of output current. This device is ideal for applications that require high power over a wide input voltage range, such as motor control, power management of handheld devices and battery powered systems.

The TPS78236DRVR is based on TI\'s voltage tracking (VT) architecture, which is a combination of a buck and boost regulator in a single package. The buck boost regulator is used to balance the output voltage of the device over the entire input voltage range. The device also has two configurable linear regulators, which can be programmed to individual voltages as needed. The linear regulators are designed to operate within the tight tolerances expected of low noise linear regulator circuits, while still providing the same regulated output over a wide range of input voltages. The input current of each linear regulator can be set to limit peak current, thus protecting the device from overload and over-voltage conditions.

The TPS78236DRVR devices contain an integrated switch-mode power supply (SMPS), which has numerous integrated features to reduce output power ripple and noise. The device also provides programmable start-up and shutdown sequencing and protection features, including output over-voltage protection, cycle-by-cycle current limit and short-circuit protection. With a fixed switching frequency and a built-in adjustable pre-bias start-up circuit, the TPS78236DRVR helps reduce design effort while still maintaining high performance and energy efficiency.

In addition to its broad array of features and capabilities, the TPS78236DRVR also provides a number of integrated diagnostics features. Its built-in watchdog timers ensure proper gate drive and current sensing, while its adjustable timer delays allow for system monitoring and protection against over-voltage and over-temperature conditions. It also includes a discrete on/off control pin that can be used to enable or disable the device.

The TPS78236DRVR is an ideal power solution for a broad range of applications that require high performance and flexibility. Its wide input voltage range, dual-channel linear regulators and built-in protection features make it well suited for motor control, industrial and consumer electronics, and battery-powered applications. In addition, its low operating current, low dropout voltage and other integrated features, such as start-up sequencing and cycle-by-cycle detection helps to conserve energy, reduce system cost and improve system reliability.
