AH8665一般的描述
AH8665是一种高性能的开关模式电源电源控制器用于低功率离线应用在典型降压解决方案中具有最小的组件。集成电路内置高击穿电压MOSFET承受高浪涌输入。不像传统的PWM控制，没有固定的AH8665家族内部时钟触发GATE驱动器，开关频率改变根据负载情况。多模式集成PWM控制，简化电路设计并达到良好的线路无负荷调节产生的音频噪声。峰值电流极限根据实际负荷情况进行变化空载时待机功率低。AH8665集功能和保护于一体欠压锁(UVLO)，每周期限流(OCP)，输出OVP，片上热关机，过负荷保护(OLP)，VDD OVP与自动恢复模式保护，等。
GENERAL DESCRIPTION
with minimum components in typical buck solution.The IC has built-in high break down voltage MOSFET to withstand high surge b.Unlike conventional PWM control, there’s no fixedinternal clock in AH8665 family to trigger the GATE driver, the switching frequency is changed according to the load condition. The multi mode PWM control is integrated to simplify circuit design and achieve good line and load regulation without audio noise generated. The peak current limit changes according to the real load condition for low standby power in no load.AH8665 integrates functions and protections of Under Voltage Lockout (UVLO), Cycle-by-cycle Current Limiting (OCP), Output OVP, On-chipThermal Shutdown, Over Load Protection (OLP), VDD OVP with Auto Recovery Mode Protection,
etc.
