The Texas Instruments TPS40170RGYR is a versatile DC/DC switching controller featuring a synchronous PWM buck topology. It is designed to operate with a wide input voltage range from 4.5V to 60V, making it suitable for various power management applications.
This controller supports an output current of up to 20A and offers a programmable switching frequency between 100 kHz and 600 kHz. Key control features include current limit, enable, frequency control, power good indication, soft start, and voltage tracking. The device operates within a temperature range of -40°C to 125°C.
The TPS40170RGYR is available in a 20-VQFN package with exposed pad, measuring 4.5 mm x 3.5 mm, and is designed for surface mount applications. Its synchronous rectification capability enhances efficiency.
Additional features include a reference voltage of 600 mV with 1% accuracy, programmable UVLO and hysteresis, voltage mode control with voltage feed-forward, and bi-directional frequency synchronization. It also provides low-side FET sensing overcurrent protection and high-side FET sensing short-circuit protection.
