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...
