The SGM6611C is a fully-integrated synchronous boost converter with a 15mΩ main power switch and a 27mΩ rectifier switch. The device provides a high efficiency and small size power solution for portable equipment. The SGM6611C features wide input voltage range from 2.7V to 12V to support applications powered with single-cell or two-cell Li-Ion/Polymer batteries. The SGM6611C has 7A continuous switch current capability and is capable of providing an output voltage up to 12.6V.
The SGM6611C uses peak current control topology to regulate the output voltage. In moderate to heavy load condition, the SGM6611C works in the Pulse Width Modulation (PWM) mode. In light load condition, the SGM6611C works in the Pulse Frequency Modulation (PFM) mode to improve the efficiency. The SGM6611C also implements a built-in 4ms soft-start function and an adjustable peak switch current limit function. In addition, the device provides 13.2V output over-voltage protection, cycle-by-cycle over-current protection, and thermal shutdown protection.
