GR8904L Low BOM Cost Power Switch Features Description Internal 600V Power MOSFET The GR8904L is a highly integrated, current mode Current Mode Control power switch with green mode control for low BOM Green Mode Control cost buck-boost application. It provides functions of 45KHz Switching Frequency low standby power consumption (<0.15W), green- Frequency Jittering mode power-saving operation for green design. The Standby Power<0.15W specific adjustable output voltage function provides the Over Load Protection feasibility for wider output application. The integrated VCC Over Voltage Protection functions of VCC OVP, OLP, and internal OTP prevent Internal Over Temperature Protection the circuit being damaged from the abnormal 9V Output voltage conditions. SOP-7 Package It minimizes the components counts and is available in SOP-7 package. Those make it an ideal design for low cost application.
