Linear Technology's LT1110CS8-12#PBF Step-Up DC/DC Converter

The LT1110CS8-12#PBF is a versatile and compact step-up DC/DC converter designed by Linear Technology, now part of Analog Devices. This power management integrated circuit is engineered to efficiently manage voltage levels in a variety of electronic applications. Its primary function is to boost lower voltage inputs to a fixed 12V output with high efficiency, which is essential for battery-powered devices and systems requiring a stable power supply.

Encased in an 8-lead SOIC package, the LT1110CS8-12#PBF is characterized by its ease of use and minimal external component requirement. It has been optimized for operation with an input voltage range of 2V to 12V, making it an ideal solution for applications running off of single-cell or multi-cell batteries, or those that need to harness power from unregulated or variable power sources.

The converter boasts a high switching frequency of up to 100kHz, which allows for the use of small, low-cost inductors and capacitors, thus reducing the overall footprint and cost of the power supply design. Furthermore, the LT1110CS8-12#PBF features internal current limiting and thermal shutdown, providing built-in protection against overcurrent and overheating conditions, thereby enhancing the reliability and longevity of the end application.

Key specifications of the LT1110CS8-12#PBF include:

• Fixed 12V output voltage
• Wide input voltage range from 2V to 12V
• High efficiency up to 85%
• Low quiescent current
• Internal 1.25A switch
• High frequency operation up to 100kHz
• Automatic shifting to power-saving Burst Mode operation at light loads
• Soft-start capability to reduce inrush current during startup

This converter is suitable for a wide range of applications, including but not limited to portable electronics, automotive systems, industrial controls, and distributed power systems. Its robust design and Linear Technology's reputation for quality make the LT1110CS8-12#PBF a reliable choice for designers looking to integrate a fixed-output step-up converter into their power management solutions.
