The TPSM8287Axx is a family of pin-to-pin step-down DC/DC power Modules with differential remote sensing and I 2C 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 solution is suitable for assembly by standard surface mount equipment. The TPSM8287Axx family implements an enhanced control scheme that supports fast transients. It 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 ±1% 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 I 2C-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 I 2C communication.
