SGM6611 12.6V, 7A Fully-Integrated Synchronous Boost Converter
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 deviceprovides 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.
