TPS65581PWPR Description

Short technical summary and product information.

The TPS65581PWPR from Texas Instruments is a highly efficient synchronous step-down DC/DC switching regulator designed for power management applications. This device offers three outputs and supports an adjustable output voltage ranging from 0.76V to 7V, with a maximum output current of 2.5A per channel. It operates with an input voltage range of 4.5V to 18V and a switching frequency of 700kHz.

 

The converter utilizes an advanced D-CAP2 control mode for fast transient response and requires no external components for loop compensation, making it compatible with ceramic output capacitors. Integrated FETs with low Rds(on) contribute to its high efficiency, particularly at low duty cycles. The device includes features such as Enable, Over Current Protection, Power Good, and UVLO.

 

Packaged in a 20-HTSSOP, the TPS65581PWPR is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA), ensuring reliable performance in various environmental conditions. The regulator also incorporates Auto-Skip Eco-mode for enhanced efficiency at light loads and provides cycle-by-cycle over-current limiting control.
