LD7578 10, 08, 2008 Green-Mode PWM Controller with HV Start-Up Circuit and OTP Protection Rev.00 General Description Features The LD7578 integrates several functions of protections in a SOP-8 package. It minimizes the component counts and the circuit space. The device provides functions of low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation. Also, the LD7578 features more protections like OLP (Over Load Protect

LD7578J 03, 03, 2009 High Voltage Green-Mode PWM Controller with Over Temperature Protection Rev. 00 General Description The LD7578J integrates several functions of protections, and EMI-improved solution in a SOP-8, or DIP-8 package to minimize the component counts and the circuit space. The device provides functions of low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation. Also, the LD7578J features more protectio
