SIP305 DC/DC Series Data Sheet 20-Watt Non-Isolated Converters Features • High efficiency  Excellent transient response  Optional sense and Power OK pins  Non-isolated  Open-frame construction  Vertical or horizontal mounting  Water washable Description 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%.
