Texas Instruments TPSM63606 Synchronous Buck Power Module
Texas Instruments TPSM63606 Synchronous Buck Power Module is a highly integrated 36V, 6A DC/DC solution that combines power MOSFETs, a shielded inductor, and passives in an Enhanced HotRod™ QFN package. The module has pins for VIN and VOUT located at the corners of the package for optimized input and output capacitor layout placement. Four larger thermal pads beneath the module enable a simple layout and easy handling in manufacturing.
With an output voltage from 1V to 16V, the Texas Instruments 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 design process's magnetics and compensation part selection.
Although designed for small size and simplicity in space-constrained applications, the TPSM63606 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 option for improved EMI, integrated VCC, bootstrap and input capacitors for 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. The TPSM63606E devices have gold bond wires, a temperature range of –55 to +105°C, and an SnPb lead finish.
