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%.
• High efficiency
• Excellent transient response
• Optional sense and Power OK pins
• Non-isolated
• Open-frame construction
• Vertical or horizontal mounting
• Water washable
