LD7552D - Green-Mode PWM Controller

Description

The LD7552D are specifically designed for the low total system cost by integrating many functions, protections, and the EMI-improved solution in a SOP-8 package which usually need a lot of extra components or circuits on the general designs.

Features

  • more protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent the circuit damage from the abnormal conditions. Features z High-Voltage CMOS Process with Excellent ESD protection z Very Low Startup Current (.

LD7552D 12/19/2007 Green-Mode PWM Controller with Integrated Protections and Adjustable OLP Delay Time REV: 00 General Description The LD7552D are specifically designed for the low total system cost by integrating many functions, protections, and the EMI-improved solution in a SOP-8 package which usually need a lot of extra components or circuits on the general designs. The implemented functions include low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation. And the LD7552D features more protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent the circuit damage from the abnormal conditions.
