TPS40222DRPRG4 Description

Short technical summary and product information.

The Texas Instruments TPS40222DRPRG4 is a fixed-frequency, current-mode, non-synchronous buck converter designed for applications requiring efficient voltage step-down. This device operates at a 1.25 MHz switching frequency and can deliver up to 1.6A of output current.

 

The input voltage range is from 4.5V DC to 8V DC, with an adjustable output voltage that can be programmed as low as 0.8V and up to 7V. The converter features internal components for soft-start, loop compensation, and slope compensation, minimizing the need for external parts.

 

Packaged in a compact 6-VSON (3x3 mm) surface-mount package, the TPS40222DRPRG4 is suitable for space-constrained designs. It operates within an ambient temperature range of -40°C to 125°C, making it robust for various environmental conditions.

 

Key features include high efficiency up to 92%, pulse-by-pulse current limit, short circuit protection, and thermal shutdown. These characteristics make it suitable for applications such as disk drives, set-top boxes, point-of-load power, and power ASIC supplies.
