High-density, 36-V input, 1-V to 20-V output, 8-A power module

Deriving from a family of synchronous buck

modules, the TPSM63610E 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 VIN and VOUT pins located at the corners of the package 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 1 V to 20 V, 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 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. Including a PGOOD indicator for sequencing, fault protection, and

output voltage monitoring.
