The SGM6029 family is a low voltage, efficient and miniature synchronous Buck converter with ultra-low quiescent current. Operating at high switching frequency (4.0MHz, TYP), miniature inductors and capacitors can be used to achieve minimal solution size. The rated load current is from 0.6A to 1A depending on the input voltage and operating frequency. For high light-load efficiency, the operating mode can smoothly and automatically change between power-save mode and PWM.
The dual-role VSEL/MODE pin sets the output voltage to one of the 16 preset values by sensing an external resistor during startup using an integrated resistor to digital (R2D) converter. After startup, this pin acts as MODE input and applying a logic high on it will force the device in the pulse width modulation (PWM) mode. This will allow using the same part for a wide range of voltage rails in different applications and offer a better output accuracy compared to the conventional external feedback resistor divider. In the forced-PWM (FPWM), the device switches at 4.0MHz (A, B and C versions) or 1.5MHz (D and E versions). High switching frequency reduces the output ripple, but at lighter loads, sacrifices the efficiency a little bit.
The SGM6029 is available in a Green WLCSP-0.74×1.09-6B package.
