FAIRCHILD SEMICONDUCTOR ML4800CP 芯片, PFC/PWM组合控制器
The is a CCM PFC + PWM Combination Controller for power factor corrected and switched mode power supplies. The Power Factor Correction PFC allows the use of smaller, lower cost bulk capacitors, reduces power line loading and stress on the switching FETs and results in a power supply that fully complies with IEC1000-3-2 specification. Intended as a BiCMOS version of the industry-standard ML4824, the ML4800 includes circuits for the implementation of leading edge, average current, boost type power factor correction and a trailing edge, pulse width modulator PWM. It also includes a TriFault Detec™ function to help ensure that no unsafe conditions will result from single component failure in the PFC. Gate-drivers with 1A capabilities minimize the need for external driver circuits. Low power requirements improve efficiency and reduce component costs. An overvoltage comparator shuts down the PFC section in the event of a sudden decrease in load.
