Overview
The TPS62067DSGR is a highly efficient synchronous step-down DC/DC converter produced by Texas Instruments. This device is part of the TPS6206x family and is designed to provide up to 2-A output current. It operates at a fixed frequency of 3 MHz and features an input voltage range of 2.9 V to 6 V, making it suitable for power conversion from 5-V or 3.3-V system supply rails. The converter automatically transitions between power save mode and fixed frequency PWM mode to maintain high efficiency over the entire load current range.
