The TPS40009DGQG4 from Texas Instruments is a DC DC switching controller that drives an N-channel MOSFET for low-voltage, non-isolated synchronous buck regulators. It supports an input voltage range from 2.25V to 5.5V and can provide an output voltage as low as 0.7V, with a maximum output voltage of 4V. The controller operates at a fixed frequency of 600kHz, offering a maximum duty cycle of 93%.
Key features include synchronous rectification, an enable pin, and soft-start functionality for controlled power-up sequences. The device is designed for applications requiring efficient power conversion, such as networking equipment, telecom equipment, base stations, servers, and DSP power supplies. It is housed in a 10-HVSSOP package, suitable for surface mount applications.
This controller is part of the TPS4000x family, which are designed for source/sink operation with VOUT prebias. The device also includes features like an internal bootstrap diode and thermal shutdown for protection. Its voltage mode control and predictive gate drive technology contribute to higher efficiency.
