The SGM6614 is a 15A switch current, fully integrated synchronous Boost converter. The integrated switch FET and rectifier switch with an 8.8mΩ low-side on-resistance and a 12.2mΩ high-side on-resistance respectively provide high conversion efficiency for portable applications. The wide input voltage range of 2.17V to 18V offers flexibility to various input supplies such as single-cell to multi-cell Lithium batteries. The device can support up to 18V output.
The SGM6614 adopts the fixed frequency peak current mode control topology for main switch FET PWM duty cycle control. The device operates in pulse width modulation (PWM) mode at medium and heavy loads, where two power FETs are alternately turned on in one switching cycle. It automatically switches to pulse frequency modulation (PFM) mode at light loads. PWM mode adopts 500kHz switching frequency.
The SGM6614 offers various protection features to improve device robustness, such as over-voltage protection, over-current protection and thermal shutdown.
The SGM6614 is available in a Green TQFN-3×2.5-11L package.
