6V Input, 15A parallelable DC-DC buck module with I2C, frequency synch, remote sense and ET-grade

The TPSM8287A1xM 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 TPSM8287A1xM family implements an enhanced

control scheme that supports fast transients. The TPSM8287A1xM 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 ±1.0% 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.
