概览

FAN49100 是一款高能效降压-升压开关模式稳压器，接受高于或低于调节输出电压的输入电压。FAN49100 使用带有同步整流的全桥结构，能够在 3.6 V 下驱动最高 2.5 A，同时调节 3.3 V 的输出。FAN49100 可在步升和步降模式之间实现无缝转换，降低了输出干扰。 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，以保持高能效。在 PFM 模式下，该零件在负载步进期间仍然能够具有卓越的瞬变响应。在中等到重型负载条件或强制 PWM 模式下，该稳压器则切换到 PWM 固定频率控制。在 PWM 模式下，该稳压器以 1.8 MHz 的标称固定频率运行，因此可减少外部组件值。

  • 24 µA PFM 静态电流典型值
  • 能效高于 95%
  • 总布局区域 = 11.61 mm2
  • 输入电压范围： 2.5 V 至 5.5 V 1.8 MHz 固定频率 PWM 运行模式
  • 自动/无缝的升压和降压模式过渡
  • 强制 PWM 和自动 PFM/PWM 模式选择
  • 0.5 µA 关断电流典型值
  • 低静态电流直通模式
  • 内部软启动和输出放电
  • 低纹波和出色的瞬态响应能力
  • 可内部设置的自动安全保护功能（UVLO、OTP、SCP、OCP）

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
