The TPS6287x -Q1 is a family of pin-to-pin 6-A, 9-A, 12-A, and 15-A synchronous step-down DC/DC converters with differential remote sensing. For each current rating, there are full-featured device variants with I 2C interface and limited-featured device variants without I 2C interface. All devices offer high efficiency and ease of use. Low-resistance power switches allow up to 15-A continuous output current at high ambient temperatures.

The devices can operate in stacked mode to deliver higher output currents or to spread the power dissipation across multiple devices.

The TPS6287x -Q1 family implements an enhanced DCS control scheme that supports fast transients with fixed-frequency operation. Devices can operate in power save mode for maximum efficiency, or forced-PWM mode for the best transient performance and lowest output voltage ripple.

An optional remote sensing feature maximizes voltage regulation at the point-of-load, and the device achieves better than ±1% DC voltage accuracy under all operating conditions.

The switching frequency is resistor-selectable through the FSEL pin. The switching frequency can be set to 1.5 MHz, 2.25 MHz, 2.5 MHz, or 3.0 MHz, or synchronized to an external clock in the same frequency range.

The I 2C-compatible interface offers several control, monitoring, and warning features, such as voltage monitoring and temperature-related warnings. The output voltage can be quickly adjusted to adapt the power consumption of the load to the performance needs of the application through the I 2C-compatible interface. The default start-up voltage is resistor-selectable through the VSEL pin.
