LTC3522 converters equivalent, synchronous 400ma buck-boost and 200ma buck converters.
* Dual High Efficiency DC/DC Converters: Buck-Boost (VOUT: 2.2V to 5.25V, IOUT: 400mA for VIN > 3V, VOUT = 3.3V) Buck (VOUT: 0.6V to VIN, IOUT: 200mA)
* 2.4V to 5..
* Flash-Based MP3 Players
* Medical Instruments
* Digital Cameras
* PDAs, Handheld PCs
* Personal Na.
The LTC®3522 combines a 400mA buck-boost DC/DC converter with a 200mA synchronous buck DC/DC converter in a tiny 3mm × 3mm package. The 1MHz switching frequency minimizes the solution footprint while maintaining high efficiency. Both converters featur.
