CR6848

CR6848 Low Cost Green-Mode PWM Controller Features Low Cost, Green-Mode PWM Very Low Start-up Current ( about 5µA) Low Operating Current ( about 2mA) Current Mode Operation Under Voltage Lockout (UVLO) Built-in Synchronized Slope Compensation Programmable PWM Frequency High-Voltage CMOS Process with ESD SOT-23-6L & DIP-8 Pb-Free Packaging Compatible with SG6848 and LD7550 Applications Switching AC/DC Adaptor Battery Charger Open Frame Switching Power Supply 384X Replacement General Description The CR6848 is a low cost, low startup current, current mode PWM controller with green-mode power-saving operation. The integrated functions such as the leading-edge blanking of the current sensing, internal slope compensation and the small SOT-23-6L package provide the users a high efficiency, low external component counts, and low cost solution for AC/DC power applications. The special green-mode control is not only to achieve the low power consumption but also to offer a non-audible-nois...
