General Description

The TPS56921 in thermally enhanced 20-pin HTSSOP package is a full featured 17V, 9A synchronous step down converter which is optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs.

After the initial power-up, the output voltage can be changed by codes sent to the IC via an I2C compatible VID Control bus.

Current mode control provides space savings and easy compensation.
