SGM6611C 12.6V, 7A Fully-Integrated Synchronous Boost Converter

2022-01-15
●GENERAL DESCRIPTION:
■The SGM6611C 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 to provide 7A continuous switch current and an output voltage range of 4.5V to 12.6V.
■The SGM6611C has two operation modes, the pulse width modulation (PWM) mode and pulse frequency modulation (PFM). The PWM mode is applied at moderate to heavy load. The PFM mode is applied at light load to improve the efficiency. The protection 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 SGM6611C is available in a Green TQFN-2×2.5-11L package.
●FEATURES:
■2.7V to 12V Input Voltage Range
■4.5V to 12.6V Output Voltage Range
■Up to 90% Efficiency (V-IN=3.3V, V-OUT=9V and I-OUT=1.5A)
■Adjustable Peak Current Limit up to 9.5A for High Pulse Current
■1.1MHz Fixed Switching Frequency (PWM Mode)
■4ms Built-in Soft-Start
■PFM Operation Mode at Light Load
■13.2V Internal Output Over-Voltage Protection
■Cycle-by-Cycle Over-Current Protection
■Thermal Shutdown
■Available in a Green TQFN-2×2.5-11L Package
