Leadtrend LD5521
The LD5521 integrate a quasi-resonant PWM control function into a SOT-26 package. It takes less components counts or circuit space, especially ideal for those total solutions of low cost. The implemented functions include low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal soft driving.| Part No. | LD5521 |

GENERAL DESCRIPTION
It also features more protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent circuit damage occurred under abnormal conditions. Furthermore, the QR jitter function could reduce the noise level and thus helps the power circuit designers to easily deal with the EMI filter by spending minimum amount of component cost and developing time. Typical ApplicationFEATURES
● Secondary-side feedback control with quasi-resonant operation● Low startup current (<5A)
● 0.5mA ultr
