45V, 100mA synkron buckkonverter
Linear Technology lancerer 45V 100 synkron buckkonverter med 'quiescent' strøm på kun 12 uA (in english).
Linear Technology announces the LTC3631, 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 synchronous rectification and a programmable peak current mode design to optimize efficiency in lower current applications. It delivers efficiencies as high as 92% and requires only 12uA of quiescent current, maximizing battery run time. Its 3mm x 3mm DFN package (or MSOP-8E) and only three tiny externals provides a highly compact solution footprint for a wide array of general purpose 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. Due to the inherent stability of the converter, no external compensation is required, thereby simplifying design and minimizing the solution footprint. It is available as an adjustable output voltage (down to 0.8V) or with fixed 3.3V or 5V output voltages.
