Cxle86124 is a high-voltage dc-dcled driver chip with multiple working modes and wide input / output range, which is internally integrated with 70V / 300m Ω power switch

Cxle86124 is a high-voltage dc-dcled driver chip with multiple working modes and wide input / output range, which is internally integrated with 70V / 300m Ω power switch. Cxle86124 can work in the mode of increasing, decreasing and increasing voltage. Its input / output voltage range can reach 3v-60vdc. Cxle86124 can adjust the output current through the external sampling resistor, and the accuracy of the output current can reach ± 3%. Cxle86124 can be PWM and analog dimming via dim pin. The cxle86124 uses a fixed switching frequency of 420khz and can use small size inductors and input / output capacitors. The current mode control makes it have excellent response speed and makes the loop compensation simpler. Cxle86124 has multiple protection functions, including overcurrent protection, input undervoltage protection, output overvoltage protection, chip overheat regulation, etc
