UPM non-isolated DC/DC buck converters deliver high power and excellent transient response in a compact
1.0” x 2.0” x 0.475” package. The UPM can provide up to 40 watts of output power at 12A output current, and
output voltages from 1.2 to 3.3V. Featuring open-frame, 100% surface-mount construction and high efficiency, the
UPM excels in difficult thermal environments.
Description
Efficiency vs. Load (5V Input)
Notes
MTBF predictions may vary slightly frommodel to model.
Specifications typically at 25°C, normal line, and full load, unless otherwise
stated.
Soldering Conditions: I/O pins, 260°C, ten seconds; fully compatible with
commercial wave-soldering equipment.
Safety: Agency approvals may vary frommodel to model. Please consult
factory for specific model information.
Units are water-washable and fully compatible with commercial spray or
immersion post wave-solder washing equipment.
