GR8836

GR8836 Green-Mode PWM Controller with Integrated Protections Features Current mode control Very low startup current Under-voltage lockout (UVLO) Non-audible-noise green-mode control Programmable switching frequency Cycle-by-cycle peak current limiting Internal leading-edge blanking Internal slope compensation Internal soft start Gate output voltage clamp Over-voltage protection (OVP) on VCC pin Over-load protection (OLP) Over-current protection (OCP) on CS pin 300mA driving capability Description The GR8836 is a highly-integrated, low startup current, current mode PWM controller with green-mode function. This function enables the power supply to easily meet even the strictest power conservation requirements. The integrated functions also include the leading-edge blanking of the current sensing, internal slope compensation, cycle-by-cycle peak current limiting, and soft start. OLP, OCP and OVP provide protection performance for fault conditions. To protect the external power MOSFET from being damaged by supply over voltage, the GR8836 OUT pin voltage is clamped to about 18V. The GR8836 improves the performance and reduces the cost of power supplies. It is with 8-pin DIP and Applications Switching AC/DC power adapter Battery charger Open-frame SMPS 6-pin SOT-26 package.
