Description for the TPS62876-Q1
The TPS62874 -Q1, TPS62875 -Q1, TPS62876 -Q1 and TPS62877 -Q1 are a family of pin-to-pin 15-A, 20-A, 25-A and 30-A synchronous step-down DC/DC converters with I 2C interface and differential remote sense. All devices offer high efficiency and ease of use. Low-resistance power switches allow up to 30-A 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 TPS6287x-Q1 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 switching frequency is selectable through the FSEL pin, and can be set to 1.5 MHz, 2.25 MHz, 2.5 MHz or 3 MHz, or synchronized to an external clock in the same frequency range.
The I 2C 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 VSEL pin.
