LED照明用ACDC控制器（不支持调光器）

LED驱动器IC BD550FHG支持绝缘、非绝缘，易于设计各种形式的低功耗转换器。外接开关用MOSFET及电流检测电阻，可实现自由度高的电源设计。通过峰值电流控制，可进行逐周期电流限制，发挥带宽和瞬态响应的优异性能。BD550FHG内置了软启动功能、脉冲串功能、逐周期过电流限制、VCC过电压保护、过负荷保护等各种保护功能。备有外部锁存端子（COMP端子），可通过外部信号停止锁存（OFF）。此功能可用于过热保护及输出过电压保护等。开关频率固定为65kHz。内置跳频功能，有助于实现低EMI。 ・ PWM frequency of 65kHz\n・ PWM current mode method\n・ Low circuit current when UVLO is ON\n (12μA at VCC=12V)\n・ Low circuit current without load\n (Burst operation when load is light)\n・ Built-in SW frequency hopping function\n・ 250nsec leading-edge blanking\n・ VCC UVLO / OVP\n・ Per-cycle over cur;
