The SGM61014 and SGM61014D are high efficiency and miniature size synchronous Buck converters with an input voltage range of 2.3V to 5.5V, optimized for low input voltage applications. This 5.8MHz high frequency device does not need external compensation and is a perfect solution for compact designs. Output voltage is fixed internally and output voltage resistor divider is no longer required. Only 470nH inductor and 10µF capacitor are needed as output filter. With its adaptive hysteresis and pseudo-constant on-time control (AHP-COT) architecture, the load transient performance is excellent and the output voltage regulation accuracy is achieved.
The device provides pulse-width modulation (PWM) and pulse frequency modulation (PFM) selection by pulling the MODE pin high and low. If the MODE pin is high, it operates in PWM mode over the whole load range. The peak efficiency is up to 92% in PWM mode. If the MODE pin is low, it works in PWM mode at heavy loads and automatically enters PFM at light loads to maintain its high efficiency, and for further efficiency improvement, it enters power-save mode (PSM) at lighter load. The typical quiescent current is 22µA at PSM mode and the efficiency of 5mA load current is maintained over 80%.
The device is available in a Green WLCSP-0.86×1.16-6B package.
