GENERAL DEscriptION

The SGM61006 is a high efficiency and miniature size synchronous Buck converter for low input voltage applications. This high frequency device does not need external compensation and is a perfect solution for compact designs. The 1.6V to 5.5V input voltage range is suitable for kinds of battery applications. It operates in PWM mode at heavy loads and automatically enters power-save mode (PSM) at light loads to maintain its high efficiency.

This device allows a wide range of output capacitors from 22μF to 100μF and even more. This flexibility makes the device a good choice for system power rails supplies. 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 is available in a Green WLCSP-0.9×1.3-6B package.
