3 Description
Deriving from a family of synchronous buck modules,
the TPSM63610 is a highly integrated 36-V, 8-A
DC/DC design 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
TPSM63610 is designed to quickly and easily
implement a low-EMI design in a small PCB footprint.
The total design 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 TPSM63610
device 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 device 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.
