SGM6610中文资料10A Fully-Integrated Synchronous Boost Converter数据手册SGMICRO规格书

描述 Description

The SGM6610 is a high-efficient synchronous boost converter. The 2.7V to 12V operation input voltage is suitable for single-cell or two-cell Li-Ion batteries. This device is capable to provide 10A switch current and an output voltage range of 4.5V to 12.6V. The SGM6610 has two operation modes, the pulse width modulation (PWM) mode and pulse frequency modulation (PFM). The PWM mode is applied at moderate to heavy loads. The PFM mode is applied at light load to improve the efficiency. An adjustable switching frequency of 200kHz to 2.2MHz can be operated in the PWM mode. 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 programmable soft-start and adjustable switch peak current limit.

The SGM6610 is available in a Green TQFN-4.5×3.5-20L package. It operates over an ambient temperature range of -40℃ to +85℃.
