Introduction

AI Translation

The LD7838 is a 700V HV start-up active PFC Flyback controller, specially designed for LED lighting application. This device operates in transition or boundary mode and integrates with completed protections required. It minimizes the components counts in either SOP-7 package. Those make it easy to design with for cost-effective applications. With High Voltage start-up technology, power factor correction and boundary mode switching control, the start-up time and resistor loss could be minimized efficiently. The circuit can easily achieve power factor is upper 0.92 to meet most of the international requirements as IEC61000-3-2 standard certifications. With completed protection built inside this IC, such as over voltage protection (OVP), over current protection (OCP), over load protection (OLP), over temperature protection (OTP), and short circuit protection (SCP), pin open / short protection. It enables the circuit to meet most safety requirements in both normal and abnormal test
