3 Description

Deriving from a family of synchronous buck modules,

the TLVM13640 is a highly integrated 36-V, 4-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 range from 1 V to 6 V,

the TLVM13640 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 TLVM13640

module offers many features for robust performance:

precision enable with hysteresis for adjustable

input-voltage UVLO, resistor-programmable switch

node slew rate for improved EMI, integrated VCC,

bootstrap, and input capacitors for increased reliability

and higher density, constant switching frequency over

the full load current range, negative output voltage

capability, and a PGOOD indicator for sequencing,

fault protection, and output voltage monitoring.
