The cxac85200 is a high-performance fixed frequency current mode controller designed for off-line and DC to DC converter applications, providing designers with a cost-effective solution

The cxac85200 is a high-performance fixed frequency current mode controller designed for off-line and DC to DC converter applications, providing designers with a cost-effective solution that requires only a minimum of external components. These integrated circuits have undervoltage lock-in with low starting current, fine tuned oscillators that can control current sampling comparator and high current totem pole output with precise duty cycle. In addition, the IC has over temperature protection, over-current protection and maximum output power protection. Cxac85200 has 16V (on) and 10V (off) undervoltage lock-in thresholds, which is very suitable for off-line converters. The maximum duty cycle of ecxac85200 can reach 100%
