SGM61307
SGM61307 is 600mA Synchronous Buck Converter manufactured by SG Micro.
DESCRIPTION
The SGM61307A/B is a synchronous Buck DC/DC converter with a wide 4V to 36V input voltage range and 600m A output current capability. This device acmodates various industrial applications powered from unregulated sources.
The SGM61307A operates in pulse skip modulation (PSM) mode at light load to boost light load efficiency, while the SGM61307B operates in forced pulse width modulation (FPWM) mode over the full load range to maintain constant frequency and reduce output voltage ripple.
The internal soft-start and loop pensation simplify the external ponents design and save users time and cost.
Protection features include current limit, hiccup mode short-circuit protection, thermal shutdown with auto recovery and output over-voltage protection.
The SGM61307A/B is available in a Green SOT-23-6 package.
