The TPSM8287Axx is a family of pin-to-pin step-down DC/DC power modules with differential remote sensing and I2C interface. The power modules integrate a synchronous step-down converter, an inductor and input 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 TPSM8287Axx family implements an enhanced control scheme that supports fast transients. The TPSM8287Axx 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.
