GENERAL DEscriptION
The SGM6611C is a fully-integrated synchronous Boost converter. The 2.7V to 12V operating input voltage is suitable for single-cell or two-cell Li-Ion/Polymer batteries. This device is capable of providing 7A continuous switch current and an output voltage range of 4.5V to 12.6V.
The SGM6611C has two operation modes, the pulse width modulation (PWM) mode and pulse frequency modulation (PFM). The PWM mode is applied at moderate to heavy load. The PFM mode is applied at light load to improve the efficiency. The protection features include output over-voltage protection at 13.2V, cycle-by-cycle over-current protection and thermal shutdown. The device also involves the functions of 4ms built-in soft-start and adjustable switch peak current limit.
The SGM6611C is available in a Green TQFN-2×2.5- 11L package.
