The SGM6039 family is a low-voltage, efficient and miniature synchronous Buck converter with ultra-low quiescent current. It can operate at a high switching frequency of 1.3MHz (TYP). The miniature inductors and capacitors can be used to achieve minimal solution size. The device features a 20nA (TYP) shutdown current and an ultra-low 245nA (TYP) quiescent current. For high light load efficiency, the operating mode can smoothly and automatically change between power- save mode and PWM. The VSET pin sets the output voltage to 18 preset values by sensing an external resistor.
The SGM6039 is available in Green WLCSP-0.8×1.05-6B and SOT-563-6 packages.
