M3TEK Preliminary Datasheet MT5086 2.7V to 30V Input 55µA Quiescent Current Synchronous Boost Controller Description The MT5086 is a high efficiency synchronous Boost PWM controller that drives all N-channel power MOSFETs to step up output voltage up to 30V. Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements, allowing the MT5086 to be used in high power Step Up applications. The 2.7V to 30V input voltage range supports a wide range of battery and AC powered inputs. The 55µA no load quiescent current extends operating run time in batterypowered systems. The adjustable operating frequency (100kHz to 1MHz) can be synchronized to an external clock with the internal PLL. The MT5086 also features a precision 1.
