The SGM61200 is an easy-to-use synchronous Buck converter with a wide 4V to 28V input voltage range and 600mA output current capability. This device can be easily used in various industrial applications powered by unregulated sources.
The SGM61200 operates at 1.1MHz switching frequency to support the use of relatively small inductors for an optimized solution size. In light load condition, the SGM61200A enters in the PFM mode to improve high efficiency, while the SGM61200B operates in forced pulse width modulation (FPWM) mode over the full load range to maintain constant frequency and reduce output voltage ripple.
Protection features include cycle-by-cycle current limit, hiccup mode short-circuit protection, and thermal shutdown in case of excessive power dissipation.
The SGM61200 is available in a Green SOT-23-6 package.
