TPSM63606 High-Density 6 A Power Module

Texas Instruments’ module is a highly-integrated 36 V DC/DC solution that comes in an enhanced HotRod™ QFN package

Texas Instruments’ TPSM63606 is a highly integrated 6 A, DC/DC synchronous buck power module that combines power MOSFETs, a shielded inductor, and passives in an enhanced HotRod QFN package. The module has pins for VIN and VOUT that are located at the corners of the package for optimized input and output capacitor layout 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 16 V, the TPSM63606 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 TPSM63606 module offers many features for robust performance including precision enable with hysteresis for adjustable input voltage UVLO, resistor-programmable switch node slew rate, and a spread-spectrum option for improved EMI. The integrated VCC, bootstrap, and input capacitors provide increased reliability and higher density, constant switching frequency over the full load current range, and a PGOOD indicator for sequencing, fault protection, and output voltage monitoring.
