The LTC3642 utilizes internal synchronous rectification and a programmable peak current mode design to optimize efficiency in lower current applications. It delivers efficiencies as high as 93% and requires only 12uA of quiescent current, maximizing battery run time. The combination of its 3mm x 3mm DFN package (or MSOP-8E) and only three tiny externals, offers a very compact solution footprint for a wide array of general purpose applications.
The LTC3642 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 minimizing the solution footprint. It is available with either an adjustable output voltage (down to 0.8V) or fixed 3.3V or 5V output voltages.
