Texas Instruments TPSM63610 Synchronous Buck DC/DC Power Module

Texas Instruments TPSM63610 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 device features VIN and VOUT pins at the package’s corners for optimized input and output capacitor placement. Additionally, four larger thermal pads beneath the module allow a simple layout and easy handling in manufacturing.

The TI TPSM63610 module has an output voltage from 1V to 20V providing a quick and easy implementation of 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 module offers many features for robust performance, including 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 entire load current range (FPWM) or variable frequency (PFM) for higher light load efficiency. This includes a PGOOD indicator for sequencing, fault protection, and output voltage monitoring.
