The TPSM8287Bxx is a family of pin-to-pin, step-down, DC/DC power modules with differential remote sensing and I2C interface. The power modules use TI’s MagPack technology to integrate a synchronous step-down converter, an inductor, input and output capacitors to simplify design, reduce external components and save PCB area. The low-profile and compact design is designed for assembly by standard surface mount equipment. The TPSM8287Bxx family implements an enhanced control scheme that supports fast transients. The TPSM8287Bxx can operate in fixed-frequency or power save mode. The remote sensing feature optimizes voltage regulation at the point-of-load and the device achieves ±0.8% DC voltage accuracy over the entire temperature range. The devices can operate in stacked, paralleled mode to deliver higher output currents or to spread the power dissipation across multiple devices. The I2C-compatible interface offers several control, monitoring, and warning features. The start-up voltage is selectable through the VSETx pins to allow a power-up without an active I2C communication.
