FAN2001/FAN2002 是一款高能效、低噪声同步 PWM 电流模式和脉冲跳过（节电）模式 DC-DC 转换器，适用于电池供电应用。它基于 2.5V 至 5.5V 的宽输入范围提供最高 1A 的输出电流。输出电压可通过外部分压器，在 0.8V 至 5.5V 的宽范围内进行外部调节。在中型和轻型负载下，使用脉冲跳过调制。应用动态电压定位，输出电压偏移至标称值以上 0.8%，以便在负载瞬变期间实现更大空间。在更高负载下，该系统则会自动切换为电流模式 PWM 控制，在 1.3 MHz 下运行。带快速瞬变响应的电流模式控制回路确保卓越的线路和负载调节。为了实现高能效，确保长电池寿命，静止电流在节电模式下降至 25µA，关断模式下源电流降至 1µA。FAN2002 采用 6 引线 SO 封装。
