General Description
The LD7560 integrated several functions of protections, and EMI-improved solution in a SOP-8/or DIP-8 package. It can minimize the component counts and the circuit space, and it’s perfect for the low cost of applications.
It provides functions of low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation. Also, the LD7560 features more protections like OLP (Over Load Protection), and OVP (Over Voltage Protection), to prevent the circuit being damaged from the abnormal conditions.
Furthermore, the LD7560 features shut down function to minimize the power loss when the LD7560’s SD pin pulled low In order to decrease standby power loss (<0.1W) for monitor application.
