(4)PFC和PWM在相同的频率上工作,在内部保持同步,其工作频率范围是15~200 k Hz,可由其10脚的外接电阻设定。(5)保护功能分两部分:一部分是热地电路的保护,通过9脚的电压采样,输入端PFC电路过压保护,欠压监测,集成电路电源欠压闭锁(11~14 V),芯片内部电源控制电路实行,11脚的PWM电路的过流保护采
(4) PFC and PWM work on the same frequency and keep in-house synchronization. The working frequency range is 15 ~ 200 k Hz and can be set by the 10-pin external resistor. (5) The protection function is divided into two parts: one is the protection of the hot circuit, the voltage sampling of 9 feet, the input PFC circuit overvoltage protection, the undervoltage monitoring, the integrated circuit power supply undervoltage lockout (11 ~ 14 V) Internal power control circuit implementation, 11-pin PWM circuit overcurrent protection mining mining
