Texas Instruments TPSM63610E Synchronous Buck DC/DC Power Module

Texas Instruments TPSM63610E Synchronous Buck DC/DC Power Module is a highly integrated 36V, 8A DC/DC solution that combines power MOSFETs, a shielded inductor, and passives in an enhanced HotRod™ QFN package. The module has VIN and VOUT pins at the package's corners for optimized input and output capacitor placement. Four larger thermal pads beneath the module enable a simple layout and easy handling in manufacturing. With an output voltage from 1V to 20V, the TPSM63610E 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.

Although designed for small size and simplicity in space-constrained applications, the Texas Instruments TPSM63610E module offers many features for robust performance: precision enable with hysteresis for adjustable input-voltage UVLO, resistor-programmable switch node slew rate and spread spectrum for improved EMI. Along with integrated VCC, bootstrap, and input capacitors for increased reliability and 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. It includes a PGOOD indicator for sequencing, fault protection, and output voltage monitoring.
