Beschreibung

The GT5152 device is a high efficiency monolithic synchronous step-down bulk regulator using current mode architecture with two integrated power MOSFETs. This device delivers up to 2A of output current over a wide operating voltage supply range from 4.75V to 24V which makes this device ideally suited for many applications such as battery powered systems, distributed power systems, networking systems and green electronics/appliances. Current mode operation provides fast transient response and excellent load and line regulation. The switching frequency of GT5152 is fixed 350kHz.

The fault condition protections such as cycle-by-cycle current limiting and over temperature hysteretic shutdown are implemented. In shutdown mode the converter draws 20μA of supply current at the maximum input supply voltage. Additional features include adjustable start, and enable.The GT5152 is available in an 8-Pin SOP package and thermal enhanced HSOP package.
