SGM61230XTN6G/TR

SGM61230XTN6G/TR is a synchronous buck converter with a wide input voltage range of 4.5V to 28V. This device can deliver up to 3A to the output over a wide input voltage. It is an easy-to-use device with power switch and peak current mode control compensation all integrated. A typical 5ms soft-start ramp is also included to minimize the inrush current. This device employs cycle-by-cycle peak current limit, output over-voltage protection and thermal shutdown with auto recovery. The current limit is implemented for both switch and has foldback feature to prevent overheating (and thermal shutdown) when an output short is detected. Auto recovery after over-current, output short, overheating or over-voltage fault maintains the system operational with no shutdown. Application includes 12V distributed power supply buses, industrial and consumer applications, white goods, audio equipment, set top boxes, digital television printers.
