描述 Description

The Micro-Point-of-Load (μPOL) SGM61013 is a family of high-efficient and high-frequency Buck DC/DC converter. Operating with a switching frequency up to 10MHz, it allows the use of small external components in both value and footprint. Different versions are available with fixed output voltages of 1.2V, 1.8V and 3.3V, delivered from an input voltage supply of 2.3V to 5.5V. A low quiescent current of only 20μA (TYP) enables high efficiency even with very light loads.
At light current load condition, the converter will automatically enter pulse frequency modulation (PFM) mode for best possible efficiency over the entire range of load currents. If PFM mode is not desired, the MODE pin can be set high to forced pulse width modulation (FPWM) operation.
The SGM61013 is available in a Green WLCSP-0.9×1.2-6B package.
