The TPS6287B10 , TPS6287B15 , TPS6287B20 and TPS6287B25 are a family of pin-to-pin 10-A,15-A, 20-A, 25-A synchronous step-down DC/DC converters with I 2C interface and differential remote sense. All devices offer high efficiency and ease of use. Low-resistance power switches allow up to 25-A output current at high ambient temperature.

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

The TPS6287Bx family implements an enhanced DCS control scheme that combines fast transient response with fixed-frequency operation. Devices can operate in power-save mode for maximum efficiency, or forced-PWM mode for 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 ±0.8% DC voltage accuracy for the full output voltage 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 load´s power consumption to the performance needs. The default start-up voltage is resistor selectable through the VSET1 and VSET2 pins.
