LTC3631EDD-5#PBF Description

Short technical summary and product information.

The LTC3631EDD-5#PBF is a high voltage, high efficiency synchronous step-down DC-DC converter manufactured by Linear Technology. This component is designed for applications requiring efficient power conversion over a wide input voltage range of 4.5V to 45V, with overvoltage lockout protection up to 60V.

 

Key electrical characteristics include a 100mA output current capability, a low quiescent current of 12μA at no load, and a feedback voltage reference of 0.8V ±1%. The converter features internal high-side and low-side power switches, eliminating the need for external compensation components. It supports 100% duty cycle operation for low dropout conditions.

 

The LTC3631EDD-5#PBF is available in compact packages such as 8-Lead DFN and 8-Lead MSOP-EP, both with a low profile of 0.75mm. These packages are suitable for space-constrained designs. The component is designed for applications including industrial control supplies, distributed power systems, portable instruments, and automotive power systems.

 

This device supports adjustable peak current limit for optimizing efficiency at lower currents and features precise RUN pin threshold with adjustable hysteresis for controlled power-up sequences. It is offered in fixed 3.3V and 5V output versions, as well as adjustable output versions.
