CX8502 5V2.4A 100KHZ car charger IC Overview CX8502 is a car charger chip, using SOP8 package, built-in MOS, input range 10V ~ 40V (typically 12V, 24V), the output of 5V, the maximum output current of 2.4A / 1A (specific value is determined by the current-sense resistor Rsen). In a heavy load (Iload demand> 2A / 1A), achieve constant function (CC), Iload actual = 2A / 1A, design precision 8%; the load is light (Iload <2A / 1A), constant pressure function (CV), Vo = 5V, design accuracy of 3%. And with the OTP, OVP, OCP, short circuit protection, cable compensation, providing light load operation. ?
