LTC3869IUFD#TRPBF Description

Short technical summary and product information.

The LTC3869IUFD#TRPBF from Analog Devices is a high-performance dual synchronous step-down switching regulator controller. It drives N-channel synchronous power MOSFETs and features a constant frequency current mode architecture, allowing for a phase-lockable frequency up to 780kHz.

 

This controller supports a wide input supply range of 4V to 38V, making it suitable for various battery chemistries. It offers independent TK/SS pins for controlled output voltage ramp-up during start-up and current foldback for MOSFET heat dissipation during short-circuit conditions. The device boasts high efficiency up to 95% and ±0.75% 0.6V output voltage accuracy.

 

The LTC3869IUFD#TRPBF is available in a 28-QFN (4x5) package, designed for surface mounting. Its control features include current limit, enable, frequency control, power good, soft start, and tracking, providing flexibility in power supply designs for applications such as server systems, telecom systems, and industrial instruments.
