Preliminary GR8875 Series Green-Mode PWM Controller with High Voltage Startup Circuit Features Applications High-Voltage (700V) Startup Circuit Adaptor/ Open Frame Power Supply Very Low Startup Current (<30uA) LCD Monitor/TV Power Supply Under-Voltage Lockout (UVLO) HV Discharge Technology to Remove X-cap Description Discharge Resistors for Good Power Saving The GR8875 series is a highly-integrated, low 50mW Standby Power startup current, current mode PWM controller with Non-Audible-Noise Green-Mode Control green-mode function, high-voltage start up circuit, 65KHz Switching Frequency with Jittering for and provides several protections such as OLP, OVP, Reducing EMI and OCP for fault conditions. A high-voltage current Cycle-by-Cycle Peak Current Limiting source supplies the start up current and the Internal Leading-Edge Blanking traditional start up resistance can be saved in order Internal Slope Compensation to reduce the start up power loss. The controller Gate Output Maximum Voltage Clamp also includes the leading-edge blanking of the Internal 6mS Soft Start current sensing, internal slope compensation and Soft Driving for Reducing EMI cycle-by-cycle peak current limiting. It is also AC Input Brownout Protection with Hysteresis integrated soft driving for reducing EMI, gate output Programmable Over Temperature Latch (OTP) voltage clamp function for protecting power Function MOSFET. Over-Voltage Protection (OVP) on VCC pin Over-Load Protection (OLP) Flexible Latch Shutdown Combination: OVP OVP+OTP 500mA Driving Capability SOP-7 /SOP-8 Green Package Ordering and Marking Information GR8875 Family Package Code RoHS Code Code G: Green (Halogen Free) Device K : SOP-8 L : PB Free Device KA : SOP-7 Family GR8875X Code SOP-7 /SOP-8 X X XXX Serial No. Code 1 Code 2 Code 1 8 9 A B G H I J Year 2008 2009 2010 2011 2016 2017 2018 2019 Code 2 1 2 3 4 9 A B C Month Jan.
