用于降压转换器并具内部栅极驱动器的 4 相 DC/DC 扩展器

LT8550 是一款用于同步降压 DC/DC 转换器的多相扩展器。它能够与任何降压 DC/DC 转换器配合工作，以通过增加额外相位来提高负载电流供应能力，对这些相位实施异相计时，以减小纹波电流和滤波电容。该器件可容易地添加相位，并不需要传送敏感的反馈和控制信号。\n\n LT8550 集成了栅极驱动器，每个器件能支持多达四个降压相位。可使用多个 LT8550，以支持多达 18 个相位。它可以准确地监察和调节每个通道的电流，以实现超卓的DC和瞬态均流。\n\n LT8550 可在 100kHz 至 1MHz 的固定频率下工作，也可同步至一个外部时钟。\n\n   • 每个芯片最多可扩展为四相\n•高达 80V 的输入或输出电压\n\n• 可与多个芯片级联，适用于极高电流应用\n\n• 支持多达 18 个不同的相位，从 20° 至 180°\n\n• 相位可以共享相位角\n\n• 出色的直流和瞬态均流\n\n• 可锁相固定频率 125kHz 至 1MHz\n\n• 支持双向电流流动 \n\n• RSENSE 或 DCR 电流检测\n\n• 无需路由敏感反馈和控制信号\n\n• 52 引脚 (7mm × 8mm) QFN 封装;

4-bit multiplexed/1-bit latched 5-bit I2C EEPROM

DESCRIPTION The primary function of the 4-bit 2-to-1 I2C multiplexer is to select either a 4-bit input or data from a non-volatile register and drive this value onto the output pins. One additional non-multiplexed register output is also provided. FEATURES • 4-bit 2-to-1 multiplexer, 1-bit
