Overview
The TPS62065DSGR is a highly efficient synchronous step-down DC/DC converter produced by Texas Instruments. It is part of the TPS6206x family, designed to provide up to 2-A output current with an input voltage range of 2.9 V to 6 V. This device is ideal for power conversion from 5-V or 3.3-V system supply rails, making it suitable for various applications requiring compact and efficient power management solutions.
The converter operates at a fixed 3-MHz switching frequency and can automatically transition between power save mode and PWM mode to maintain high efficiency across the entire load current range. The power save mode is optimized for low output voltage ripple, and for low noise applications, the device can be forced into fixed frequency PWM mode by adjusting the MODE pin.
