概览
FAN53526 是一款步降开关稳压器，基于 2.5V 至 5.5V 的输入电压提供可数字编程的输出。输出电压可通过 I2C 接口进行编程，能够驱动最高 3.4MHz。FAN53526 适应带有同步整流的专属结构，能够以 80% 以上的能效驱动 3.0A 连续电流，同时在低至 10mA 的负载电流下保持该能效。该稳压器以 2.4MHz 的标称固定频率运行，降低了外部组件值。还可以增加附加输出电容，以改善瞬变负载下的调节，而且不会影响稳定性。在中等和轻型负载条件下，使用脉频调制 (PFM) 以节能模式运行该器件，且室温下的典型静止电流为 50 µA。即使静止电流如此之低，该零件在较大负载摆幅期间仍然具有绝佳的瞬变响应。在更高负载下，该系统则会自动切换为固定频率控制，在 2.4MHz 下运行。在关断模式下，电源电流降至 1µA 以下，减少了功耗。如果需要固定频率，则可以禁用 PFM 模式。FAN53526 采用 15凸块，1.310mmx 2.015mm，0.4mm 球形焊点间距 WLCSP 封装。
