3 Description
The TPS6287B10, TPS6287B15, TPS6287B20,
TPS6287B25, and TPS6287B30 are a family of pinto-
pin, 10A, 15A, 20A, 25A, and 30A synchronous
step-down DC/DC converters with I2C interface and
differential remote sense. All devices offer high
efficiency and ease of use. Low-resistance power
switches allow up to 30A 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 I2C 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.
