The TPS6287x-Q1 is a family of pin-to-pin 6A, 9A, 12A, and 15A synchronous
step-down DC/DC converters with differential remote sensing. For each current
rating, there are full-featured device variants with I2C interface and
limited-featured device variants without I2C interface. All devices offer
high efficiency and ease of use. Low-resistance power switches allow up to 15A
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 a fixed-frequency DCS-Control scheme that
supports fast transients. The devices can operate in power save mode for maximum
efficiency, or forced-PWM mode for the best transient performance and lowest output
voltage ripple.
The remote sensing feature allows
voltage regulation at the point-of-load, hence 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 1.5MHz, 2.25MHz, 2.5MHz, or 3.0MHz, or synchronized to an
external clock in the same frequency 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 power consumption of the load to
the performance needs of the application through the I2C-compatible
interface. The default start-up voltage is resistor-selectable through the VSEL
pin.
