SGMicroelectronics has released the SGM61330, a 3.8V to 36V input, 3A, synchronous buck converter. This device is suitable for industrial power supplies, telecommunications and data communication systems, as well as general-purpose wide-input-voltage regulation applications.

The SGM61330 is a synchronous buck converter with an internal compensation mechanism, featuring a wide input voltage range of 3.8V to 36V and an output current capability of up to 3A. Its design is optimized to easily handle various industrial applications powered by unstable power sources. The peak current mode control technology used in this device makes it easy to implement compensation and per-cycle current limiting.

The SGM61330 has a static current of only 28μA (typical value) and a ultra-low shutdown current of 2μA (typical value), making it an ideal choice for battery-powered systems and extending battery life. The built-in compensation function further simplifies the design process, achieving a fast and compact solution.

In medium or heavy load conditions, the SGM61330 operates at a fixed frequency, while in light load conditions, it automatically switches to pulse frequency modulation (PFM) mode to optimize efficiency.

The EN function is set by an enable divider, which not only simplifies the adjustment of under-voltage lockout (UVLO) but also enables the device’s on/off control and power sequencing. Additionally, the SGM61330 provides thermal shutdown and output short-circuit protection (hiccup mode) to ensure system stability and safety.

The SGM61330 is packaged in a green TQFN-2×3-12AL environmentally friendly package.
