Description

The GR8903A is a highly integrated, current mode power switch with green mode control for low BOM cost buck and flyback application. It provides functions of low standby power consumption (<0.15W), green- mode power-saving operation for green design. The integrated functions of VCC OVP, OLP, and internal OTP prevent the circuit being damaged from the abnormal conditions.

It minimizes the components counts and is available in SOP-7 package. Those make it an ideal design for low cost application.
