SGM6614

18V Output, 15A, FullyIntegrated

Synchronous Boost Converter

GENERAL DESCRIPTION

FEATURES

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.

● 2.17V to 18V Input Voltage Range

● 4.5V to 18V Output Voltage Range

● 2.4V Minimum Input Voltage for Startup

● 15A (TYP) Peak Switch Current Limit

● 8.8mΩ Low-side and 12.2mΩ High-side

MOSFETs

● Fixed 500kHz Switching Frequency

● High Efficiency

 Up to 94.42% Efficiency at V_IN= 3.6V, V_OUT= 13V,

and I_OUT= 2A

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.

 Up to 97.07% Efficiency at V_IN= 7.2V, V_OUT= 16V,

and I_OUT= 2.5A

● 85µA (TYP) Quiescent Current into VOUT Pin

● Less than 1.5µA Shutdown Current

● Auto PFM at Light Loads

● 19V Output Over-Voltage Protection

● Cycle-by-Cycle Over-Current Protection

● Thermal Shutdown

The SGM6614 offers various protection features to

improve device robustness, such as over-voltage

protection, over-current protection and thermal shutdown.

● Available in a Green TQFN-3×2.5-11L Package
