SGM6332

The SGM6332 is a current-mode buck converter with an internal power MOSFET switch. This device has a fixed switching frequency of 1.4MHz. It can efficiently provide up to 3A output load current over a wide input supply range from 4.5V to 18V with excellent load and line regulation responses.

In addition, the SGM6332 is an efficient, 91% peak efficiency when the device is in operation. The shutdown supply current consumed is less than 18μA. Protection features include cycle-by-cycle current limit and thermal shutdown. The device also includes an internal soft-start and an external adjustable soft-start function to limit the inrush current and prevent the overshoot of output voltage.

The SGM6332 is available in a Green SOIC-8 (Exposed Pad) package and also minimizes the external components of the device to complete a 3A buck DC/DC converter solution.
