The TPS62742DSST is a special purpose voltage regulator specifically designed for use in harsh environmental conditions. It is an adjustable 3-A step-down converter featuring the company’s D-CAP2 mode control, below-1-nA quiescent current, and a wide input voltage range up to 40 V.

TPS62742DSST is based on advanced control architectures to meet demanding performance requirements. It provides integrated active output voltage tracking and programmable current monitoring, as well as a comprehensive enable/disable feature set. The device combines low-noise, low-power performance and low output voltage tracking accuracy in a small package.

The applications of TPS62742DSST primarily include automotive and industrial applications. The automotive applications include airbag control units, hybrid vehicle power supplies, instrument cluster systems, and low-emission motor control and storage systems.

Due to its efficient design, the TPS62742DSST also has a wide range of industrial applications. Examples include managed power supplies, diesel engine control, remote power management systems, lighting control systems, vending machines, and temperature and humidity controllers.

The TPS62742DSST power regulator works on the principle of buck-boost. It uses a buck-boost topology in which the input voltage, output voltage, and input-output current are connected in series across the power switch to ensure proper control and regulation of the output voltage. The regulator utilizes a voltage control loop that adjusts the switching frequency of the power switch to regulate and maintain the output voltage.

An advanced D-CAP2 mode control is featured in TPS62742DSST. This advanced control technology operates in pulse skipping, pulse frequency modulation, and pulse-width modulation modes, and it also features a cycle-by-cycle current limit. This enables superior transient performance with high efficiency and low output voltage ripple, under heavy load steps.

The quiescent current in the TPS62742DSST is low, below 1 nA. This is accomplished through a state-of-the-art power management design, which optimizes switching frequencies and minimizes power dissipation. TPS62742DSST is also integrated with over-current and over-voltage protection, as well as a comprehensive enable/disable feature set.

In summary, TPS62742DSST is a special purpose voltage regulator designed for harsh environmental conditions. It utilizes an advanced D-CAP2 mode control, below 1 nA quiescent current, and a wide input voltage range up to 40 V. The device has a wide range of applications in automotive and industrial applications. Its principle of operation is based on a buck-boost topology.
