LTC3631EMS8E#TRPBF - High Efficiency, Low Noise 100mA Synchronous Step-Down DC/DC Converter

The LTC3631EMS8E#TRPBF is a high-performance synchronous step-down DC/DC converter brought to you by Linear Technology, a leader in innovative power management solutions. This efficient and compact integrated circuit is designed to deliver up to 100mA of continuous output current from a wide input voltage range of 4.5V to 45V, making it an ideal choice for automotive, industrial, and telecommunications applications where input voltages can vary widely.

With its high efficiency, the LTC3631EMS8E#TRPBF can maintain a low quiescent current of only 12μA, which is beneficial for battery-powered systems where power conservation is crucial. The device operates using a constant frequency, current mode architecture, which provides excellent line and load regulation and low output ripple, ensuring stable and reliable operation even under varying conditions.

The converter features a programmable frequency range from 50kHz to 1MHz, allowing designers to optimize the size of external components and maximize efficiency. Additionally, the LTC3631EMS8E#TRPBF incorporates Burst Mode® operation, which further reduces quiescent current during light load conditions, extending battery life in portable applications.

For protection and safety, the LTC3631EMS8E#TRPBF includes a range of features such as over-temperature protection, over-current protection, and a power good flag that signals when the output voltage is within regulation. The device is available in an MSOP-8 package, which is suitable for space-constrained applications.
