Preliminary GR8837R Green-Mode PWM Controller with Hiccup Protection Features Description Current Mode Control The GR8837R is a highly-integrated, low startup Standby Power below 100mW current, current mode PWM controller with Under-Voltage Lockout (UVLO) green-mode function. The integrated functions also Non-Audible-Noise Green-Mode Control include the leading-edge blanking of the current 65KHz Switching Frequency sensing, internal slope compensation, soft start Internal Leading-Edge Blanking OLP, and OCP. Besides, The RTL pin latch function Internal Slope Compensation by injecting a high over 3.5V to provide OVP latch Internal Soft Start off and low below 1V to provide OTP latch off Gate Output Voltage Clamp protection. These functions enable the power supply Jitter and Soft Driving for Reducing EMI to easily meet even the strictest power External OVP Latch Mode requirements. External OTP Latch Mode The GR8837R improves the performance and Over-Load Protection (OLP)- -Auto Recovery reduces the cost of power supplies. It is with 8-pin Mode DIP and 6-pin SOT-26 package. Vcc OVP Protection- Auto Recovery Mode 300mA Driving Capability .
