SG-Micro SGM6610

Beschreibung

The SGM6610 is a high power density, fully integrated synchronous boost converter with an 11mΩ power switch and a 13mΩ rectifier switch to provide a high efficiency and small size solution in portable systems. The SGM6610 has a wide input voltage range from 2.7V to 12V to support applications with single cell or two cell Lithium batteries. The device has 10A switch current capability and is capable of providing an output voltage up to 12.6V. The SGM6610 uses constant frequency peak current control topology to regulate the output voltage. In moderate to heavy load condition, the SGM6610 works in the Pulse Width Modulation (PWM) mode. In light load condition, the device works in the Pulse Frequency Modulation (PFM) mode to improve the efficiency. The switching frequency in the PWM mode is adjustable ranging from 200kHz to 2.2MHz by an external resistor. The SGM6610 also implements a programmable soft-start function and an adjustable switching peak 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 SGM6610 is available in Green TQFN-4.5×3.5-20L package. It operates over an ambient temperature range of -40℃ to +85℃.
