The Texas Instruments TPS65270RGET is a monolithic, dual synchronous buck regulator designed for a wide operating input voltage range from 4.5V to 18V. It provides two output channels, capable of delivering up to 2A for Buck 1 and 3A for Buck 2.
This regulator features a precision 0.8V reference with ±1% accuracy and allows for adjustable output voltages. The switching frequency can be set externally between 300 kHz and 1.4 MHz. It supports startup with a pre-biased output and includes dedicated enable and soft-start pins for each buck converter, offering flexibility in power sequencing.
The TPS65270RGET utilizes constant frequency peak current-mode control for simplified compensation and fast transient response. It incorporates cycle-by-cycle overcurrent protection and hiccup mode operation for fault conditions. The device operates out-of-phase (180°) to minimize input capacitance and power supply noise. It is available in a 24-lead VQFN (4x4 mm) package suitable for surface mounting.
Applications for this regulator include DTVs, DSL modems, cable modems, set-top boxes, car DVD players, home gateways, access point networks, and wireless routers.
