SGM61310

The SGM61310 is a synchronous Buck converter with a wide input voltage range of 4V to 36V. This device can deliver up to 1A to the output over a wide input voltage. It is an easy-to-use device with power switches and peak current mode control compensation all integrated in a small 6-pin package. A typical 1.8ms soft-start ramp is also included to minimize the inrush current. This device can be easily used in various industrial applications powered from unregulated sources. 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 switches 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. The SGM61310 operates at 700kHz switching frequency to support use of relatively small inductors for an optimized solution size. In light load condition, the SGM61310A enters in the pulse skip modulation (PSM) mode to improve high efficiency, while the SGM61310B works in the forced pulse width modulation (FPWM) mode to achieve low output ripple. The SGM61310 is available in a Green SOT-23-6 package.
