GR8837

GR8837 Green-Mode PWM Controller with Latch Protection Features Current mode control Standby power below 100mW Under-voltage lockout (UVLO) Non-audible-noise green-mode control 65KHz switching frequency Internal leading-edge blanking Internal slope compensation Internal soft start Gate output voltage clamp Jitter and soft driving for reducing EMI External OVP Latch off mode External OTP Latch off mode Over-load protection (OLP)-Auto recovery mode Vcc OVP protection- latch Mode 300mA driving capability Description The GR8837 is a highly-integrated, low startup current, current mode PWM controller with green-mode function. The integrated functions also include the leading-edge blanking of the current sensing, internal slope compensation, soft start OLP, and OCP. Besides, The RTL pin latch function by injecting a high over 3.5V to provide OVP latch off and low below 1V to provide OTP latch off protection. These functions enable the power supply to easily meet even the strictest power requirements. The GR8837 improves the performance and reduces the cost of power supplies. It is with 8-pin DIP and 6-pin SOT-26 package Application Switching AC/DC Adapter Battery Charger Open frame SMPS Ordering and Marking Information DIP-8 SOT-26 Code 1 Year Code 2 Month 8 2008 1 Jan. 9 2009 2 Feb.
