SIP305 Datasheet, PDF (1/3 Pages) Power-One – NON-ISOLATED, 20 WATT

SIP305 SERIES - NON-ISOLATED, 20 WATT
DESCRIPTION
SIP305 non-isolated step-up DC/DC converters deliver
high efficiency and excellent transient response in an
industry-standard SIP package. Measuring 2.5” x 0.55”
x 0.31”, the SIP305 can provide up to 20 watts of output
power. The SIP305 is the perfect tool for designers who
are tight on board space and need to augment 3.3V
circuit boards with 5V. Operating over a wide 3.0 to
4.0V input range and a frequency of 400 kHz, the
SIP305 features surface-mount construction and an
efficiency of 90%.

Notes
† _{MTBF predictions may vary slightly from model 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 from model 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.
