3 Description
The TPS6287x 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 family implements an enhanced DCScontrol
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.
