概览

RAA223021 是一款具有超低待机功率的通用的输入 AC/DC 开关稳压器，其具备 700V 集成 MOSFET，能够在降压模式下提供高达 12W 的输出功率，可在反激模式下提供高达 12W 的输出功率。 它支持低至 3.3V 的输出电压，无需额外的 LDO。

RAA223021 将恒关时间控制与脉冲调频 (PFM) 相结合，用于轻负载操作。 恒关时间控制开关频率比可听频率高出约 43kHz。 PFM 消除了任何潜在的可听噪声，同时提供了卓越的轻负载效率和超低功耗（空载时 < 20mW）。 效率高达 80%。 内置的频率抖动进一步降低了 EMI 噪声频谱。

RAA223021 还具有输入功率不足保护功能，可防止输入电路在低输入电压下的过电流，并在输出故障条件（如短路、过载、过电压和开路反馈）下进行打嗝保护。

RAA223021 采用 SOIC-7 封装。

  • 超低待机功率 (< 20mW)
  • 无可听噪声
  • 低静态电流 (< 80μA)
  • 输出电压低至 3.3V
  • 频率抖动带来低 EMI
  • 7 Ld SOIC 封装
  • 可编程 PFM 允许优化 COUT，以满足各种备用电源需求
  • 保护功能：短路保护 (SCP)、过载保护 (OLP)、过电压保护 (OVP)、开反馈保护、超温保护 (OTP)
