SGM6611 - Synchronous Boost Converter

Description

The SGM6611 family includes the SGM6611A and the SGM6611B.

The SGM6611 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.

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 SGM6611A and SGM6611B are both available in a Green TQFN-2×2.5-11L package.

SGM6611 12.6V, 7A Fully-Integrated Synchronous Boost Converter GENERAL DESCRIPTION The SGM6611 family includes the SGM6611A and the SGM6611B. The SGM6611 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. It also has an adjustable switching frequency ranging from 200kHz to 2.2MHz. The SGM6611 family has two operation modes, the pulse width modulation (PWM) mode and pulse frequency modulation (PFM). The SGM6611 family adopts the PWM mode at moderate to heavy load. The PFM mode is applied at light load by SGM6611A to improve the efficiency.
