3 Description
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 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 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.
