SGM6611 12.6V, 7A Fully-Integrated Synchronous Boost Converter PRELIMINARY DATASHEET
SGM6611B. The SGM6611 is a fully-integrated
synchronous boost converter with a 16mΩ 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 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
the Green TQFN-2×2.5-11L package.
