(RLF) QFN package
– 85-mm2 solution size (single sided)
– Low EMI: Meets CISPR11 radiated emissions
– Excellent thermal performance:
Up to 14 W output power at 85ºC, no airflow
– Standard footprint: single large thermal pad
and all pins accessible from perimeter
• 3.8 V to 36 V input voltage range
• Output voltage range: 1 V to 7 V
• Efficiency up to 95%
• Power-good flag
• Precision enable
• Built-in hiccup-mode short-circuit protection, over-
temperature protection, start-up into pre-bias
output, soft start, and UVLO
• Operating IC junction range: –40°C to +125°C
• Operating ambient range: –40°C to +105°C
• Shock and vibration tested to Mil-STD-883D
• Pin compatible with: 3-A TPSM53603
and 4-A TPSM53604
• Create a custom design using the TPSM53602
with the WEBENCH® Power Designer
3 Description
The TPSM53602 power module is a highly integrated
2-A power solution that combines a 36-V input, step-
down, DC/DC converter with power MOSFETs, a
shielded inductor, and passives in a thermally-
enhanced QFN package. The 5-mm x 5.5-mm x 4-
mm, 15-pin QFN package uses routable lead-frame
technology for enhanced thermal performance, small
footprint, and low EMI. The package footprint has all
pins accessible from the perimeter and a single large
thermal pad for simple layout and easy handling in
manufacturing.
The total solution requires as few as four external
components and eliminates the loop compensation
and magnetics part selection from the design
process. The full feature set includes power good,
programmable UVLO, prebias start-up, overcurrent,
and overtemperature protections, making the
TPSM53602 an excellent device for powering a wide
range of applications.
