2.7V to 30V Input 55μA Quiescent Current Synchronous Boost Controller
Description Features
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 applicati***. 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 battery-powered systems.
The adjustable operating frequency (50kHz to 1MHz) can be synchronized to an external clock with the internal PLL. The MT5086 also features a precision 1.215V reference and a power good output indicator. The MODE/SYNC pin selects between pulse skipping mode and force PWM mode at light loads.
