LTC1044ACS8#TRPBF - Voltage Converter IC from Linear Technology

The LTC1044ACS8#TRPBF is a versatile voltage converter integrated circuit (IC) designed and manufactured by Linear Technology, a leader in high-performance analog integrated circuits. This IC is a part of Linear's LTC1044 series and is housed in an 8-lead SOIC package, making it suitable for a wide range of applications where space is at a premium.

This high-performance charge pump voltage converter can efficiently convert a positive voltage in the range of 1.5V to 15V to the corresponding negative voltage of the same magnitude. It is capable of delivering up to 20mA of output current with a typical voltage conversion efficiency of 99.9% for small load currents, which decreases to 90% as the load current approaches its maximum rating.

The LTC1044ACS8#TRPBF operates at a quiescent current of just 100µA, which is a critical feature for battery-powered applications where power efficiency is paramount. Additionally, it features a low power shutdown mode that reduces the supply current to only 20µA, further conserving battery life when the device is not in active use.

This IC is ideal for applications that require a negative supply voltage generated from a positive input, such as operational amplifier systems, memory bias generators, and portable instruments. Its high frequency operation of 10kHz to 45kHz (which can be externally adjusted) allows for small capacitors, thus reducing the overall size and cost of the system.

The LTC1044ACS8#TRPBF is also characterized by its ease of use, requiring only two external capacitors to complete the voltage conversion function. This makes it a convenient solution for designers looking to implement a negative voltage rail without the complexity and space requirements of inductive switching regulators.

In summary, the LTC1044ACS8#TRPBF from Linear Technology is a reliable and efficient solution for generating a negative voltage from a positive input, with its compact size, low power consumption, and minimal external component requirements making it an excellent choice for a wide array of electronic applications.
