3 Description
The TLVM13630 synchronous buck power module
is a highly integrated 36-V, 3-A 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 range from 1 V to 6 V,
the TLVM13630 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 TLVM13630
module offers many features for robust performance:
precision enable with hysteresis for adjustable inputvoltage
UVLO, integrated VCC, bootstrap and input
capacitors for increased reliability and higher density,
constant switching frequency over the full load current
range for enhanced load transient performance,
negative output voltage capability for inverting
applications, and a PGOOD indicator for sequencing,
fault protection, and output voltage monitoring.
