Description

The SGM6611 family includes the SGM6611A and the SGM6611B. The SGM6611 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 SGM6611 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 SGM6611 has 7A continuous switch current capability and is capable of providing an output voltage up to 12.6V. The SGM6611 uses peak current control topology to regulate the output voltage. In moderate to heavy load condition, the SGM6611 family works in the Pulse Width Modulation (PWM) mode. In light load condition, the SGM6611A works in the Pulse Frequency Modulation (PFM) mode to improve the efficiency, while the SGM6611B still works in the PWM mode to avoid application problems caused by low switching frequency. The switching frequency in the PWM mode is adjustable from 200kHz to 2.2MHz. The SGM6611 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. The SGM6611A and SGM6611B are both available in a Green TQFN-2×2.5-11L package.
