TPS53353DQPR Description

Short technical summary and product information.

The TPS53353DQPR from Texas Instruments is a high-efficiency, 20A synchronous SWIFT™ buck converter designed for power management applications. It supports an input voltage range of 1.5V to 15V and provides an adjustable output voltage from 0.6V to 5.5V.

This device features D-CAP™ mode control for fast transient response and selectable switching frequencies between 250 kHz and 1 MHz. Key integrated features include adjustable current limit, overcurrent protection, power good signal, prebias startup, soft-start, synchronous rectification, and UVLO (undervoltage lockout).

The TPS53353DQPR is available in a 22-LSON-CLIP (6x5 mm) package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA), with a typical quiescent current of 0.32 mA and a maximum duty cycle of 90%.

This converter is designed for applications requiring high output current and efficiency, such as point-of-load regulation in computing and industrial systems.
