TPS62065QDSGRQ1

The TPS62065QDSGRQ1 from Texas Instruments is an automotive-qualified step-down DC/DC converter designed for efficient power management. This device operates with an input voltage range from 2.9V to 6V and can deliver up to 2A of output current.

Key electrical specifications include a 3MHz switching frequency, which allows for the use of smaller external components, and a maximum duty cycle of 100% for lowest dropout voltage. It features adjustable output voltage with a minimum of 0.8V and a maximum of 6V, and an output voltage accuracy of ±1.5% in PWM mode. The converter boasts high efficiency, up to 97%, and a low quiescent current of typically 18µA.

This regulator is housed in an 8-WSON (2x2) package, suitable for surface mount applications. It includes features such as Enable, Light load efficiency, Output discharge, Spread Spectrum, and Synchronous Rectification. The operating temperature range is -40°C to 125°C (TJ), making it suitable for demanding automotive environments.

Additional features include power-save mode, a power-good output, and an output capacitor discharge function. The spread spectrum feature helps in reducing electromagnetic interference (EMI).
