SIP305 SERIES - NON-ISOLATED, 20 WATT

REV. 08/01

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%.
