The BLL2206 is a high-efficiency, DC-to-DC step-down switching regulators, capable of delivering up to 6A of output current. The device operates from an input voltage range of 2.3V to 5.5V and provides an output voltage from 0.55V to 3.3V.
The BLL2206 works at a nominal fixed frequency of 4MHz which allows the use of small external components, such as ceramic input and output capacitors, as well as small inductors, while still providing low output ripples. Efficiency is maximized through the integrated 11.5mΩ/6.5mΩ MOSFETs. Using PFM mode in light load and PWM mode in heavy load makes the BLL2206 keep high efficiency in full range. Low noise output along with excellent efficiency makes BLL2206 an ideal replacement for large power consuming linear regulators.
The BLL2206 includes under-voltage lockout, current limiting, short-circuit protection and thermal shutdown protection.
The BLL2206 is available in small DFN-9 package which size is 3mm*2mm*0.75mm.
