    description

    LTM®8040 是一款固定频率 1A 降压型 DC/DC μModule®Voltage regulator，专为用作一个恒定电流源而设计。内部电路负责监视输出电流，以提供准确的电流调节，这非常适合于驱动高电流 LED。高输出电流准确度在一个很宽的电流范围内 (从 35mA 至 1A) 得以保持，因而在 2.5V 至 13V 的输出电压范围内实现了一个宽调光范围。独特的 PWM 电路提供了一个 250:1的调光比，从而消除了采用 LED 电流调光时所常见的色偏现象。

    凭借其 4V 至 36V 的宽输入范围，LTM8040 可调节各种各样的电源，包括四节电池和5V 逻辑电源轨、未调整的墙上适配器、铅酸电池和分布式电源等等。

    LTM8040 采用耐热增强型的紧凑 (15mm x 9mm x 4.32mm) 模压树脂焊盘网格阵列 (LGA) 封装，适合采用标准的表面贴装设备来进行自动化装配。LTM8040 是无铅型器件，并符合 RoHS 标准。
