同步整流控制器

WS9901是一款高性能、高集成度、具有快速关 断特性的单通道同步整流控制器。支持CCM,QR和DCM的多模式工作。通过智能的控制MOSFET的开通 和关断，可替代反激或者正激变换器次级整流的肖特基二极管来实现效率的提高。\n\nWS9901 内置自供电电路，可从 SW 或 VOUT 分别给 VCC 充电，从而可以使 IC 在输出电压很低时可以正常工作，如在电池充电时低输出电压或输出短路时。WS9901支持放在正端时，可以满足正常供电而无需辅助绕组供电。WS9901采用稳先微专利的振铃检测电路防止在 DCM 下 Vds 振荡引起的误开通。 • 支持CCM，QR和DCM多模式工作\n• 支持高频有源钳位反激拓扑\n• 支持宽输出电压范围，可低至0V\n• 支持放置正端整流而无需辅助绕组供电\n• 振铃检测技术防止DCM下振铃引起的误开通高的驱动电压可以选择标准的MOS管\n• 大约30ns的关断延时\n• 支持<300KHz的开关频率静态电流低至110uA满足能效6要求\n• SOP8封装\n• WS9901 提供 SOP8 封装;

Universal Relay Driver

General Description The Supertex HV9901 is a BiCMOS/DMOS universal relay driver that employs PWM switching techniques. It is designed for efficient and energy-saving operation of a low voltage relay with supply voltages ranging from 8 to 450V DC through utilization of the relay coils’ inductance.
