The TPS6287x devices are synchronous step-down (buck) DC/DC converters. These devices use an enhanced DCS control topology to achieve fast transient response while switching with a fixed frequency. Together, with the low output voltage ripple, high DC accuracy, and differential remote sensing, these devices are ideal for supplying the cores of modern high-performance processors.

The family of devices includes 6A, 9A, 12A, and 15A devices. To further increase the output current capability, the user can combine multiple devices in a “stack”. For example, a stack of two TPS62873 devices have a current capability of 30A. Each device of a stack must have the same current rating to avoid that one device enters current limit too early.

For each current rating, there are full-featured devices with an I²C interface and limited-featured devices without an I²C interface (see the Device Options). The user can use a device variant without I²C in exactly the same way as a device variant with I²C, except that:

• The user must connect the unused SCL and SDA pins to GND.
• The user must be aware of the (fixed) factory settings for parameters and functions that are programmable in the I²C device variants.
