SIP305 SERIES - NON-ISOLATED, 20 WATT

REV. 02/02

SIP305 non-isolated step-up DC/DC converters deliver

high efficiency and excellent transient response in an

industry-standard SIP package. The SIP305 can provide

up to 20 watts of output power, and 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%.

General

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.
