            TPSM63610 Synchronous Buck DC/DC Power Module
                    Texas Instruments' small, highly-integrated DC/DC solution is ideal for simplicity in space-constrained applications
    

Texas Instruments' TPSM63610 is a highly-integrated 36 V, 8 A DC/DC solution that combines power MOSFETs, a shielded inductor, and passives in an enhanced HotRod™ QFN package. The module has V_IN and V_OUT pins that are located at the corners of the package for optimized input and output capacitor placement. The four larger thermal pads beneath the module enable a simple layout and easy handling in manufacturing. With an output voltage range of 1 V to 20 V, the TPSM63610 is designed to quickly and easily implement a low-EMI design in a small PCB footprint.

The total solution requires as few as four external components and eliminates the magnetics and compensation part selection from the design process. The TPSM63610 is designed for small size and simplicity in space-constrained applications, as well as robust performance with features including precision enable with hysteresis for adjustable input voltage UVLO, resistor-programmable switch node slew rate and spread spectrum, and a spread spectrum option for improved EMI. The integrated V_CC, bootstrap, and input capacitors offer increased reliability and a higher density.

The module can be configured for constant switching frequency over the full load current range (FPWM) or variable frequency (PFM) for higher light-load efficiency. The TPSM63610 includes a PGOOD indicator for sequencing, fault protection, and output voltage monitoring.
