Linear Technology Announces LTC3631, 45V Input-Capable Synchronous Buck Converter with Only 12 micro A Typical DC Current

Mon, May 18th, 2009. In Automotive, Vehicle, Embedded Device, Industrial, Power, Semiconductor

The LTC3631 is a 45V input-capable synchronous buck converter that can deliver up to 100mA of continuous output current. It operates from an input voltage range of 4.5V to 45V with transient protection up to 60V, making it ideal for automotive and industrial control loop applications. The LTC3631 utilizes internal high side and synchronous power switches which draw only 12uA at no load while maintaining output voltage regulation, making it ideal for always on battery-powered applications. The LTC3631 can supply up to 100mA load current and
features a programmable peak current limit that provides a simple method for optimizing efficiency in lower current applications. The LTC3631’s combination of Burst Mode® operation, integrated power switches, low quiescent current, and programmable peak current limit provides high efficiency over a broad range of load currents…
