Synchronous Buck Converter Delivers 93% Efficiency & Requires Only 12uA Quiescent Current
Linear Technology has announced the LTC3632, a 50V input-capable synchronous buck converter that delivers up to 20mA of continuous output current from a 3mm x 3mm (or MSOP8-E) package. It operates from an input voltage range of 4.5V to 50V with protection up to 60V, making it ideal for automotive and industrial 4mA to 20mA control loop applications.The
The LTC3632 utilizes internal high side and synchronous power switches which draw only 12uA at no load while maintaining output voltage regulation, making it well suited for always-on battery-powered applications. Due to the inherent stability of the converter, no external compensation is required, thereby minimizing the solution footprint. It is available with an adjustable output voltage (down to 0.8V).
