2.5A 可调降压-升压射频直流/直流转换器

LM3248 是一款 PWM/PFM 升压-降压直流/直流转换器，此转换器在宽电压范围内有效利用电池电量。 此器件架构适用于先进的 RF 前端系统，此系统要求动态电压和电流以支持运行在 2G/3G/4G 和 3GPP/LTE 模式下的收敛式功率放大器架构。 例如，LM3248 被设计用来在保持某些全新功耗减少 CMOS 功率放大器 (PA) 所要求的 PFM 模式的同时，产生更高的输出电压。 超快速的升压-降压功能减少 RF PA 系统开销功率耗散，从而延长了电池所支持的通话时间。 此器件将运行在 2.7V 至 5.5V 的 VIN 电压范围内，并且可在 2.5A 的最大电流负载下，在 0.4 • 0.4V 至 4.0V（典型值）的可调输出电压 VOUT\n• 2.7V 至 5.5V 的输入电压范围 VIN\n• 支持无缝转换的升压-降压和降压（升压-旁路）工作模式\n• 2.5A 负载电流能力\n• 高转换效率（典型值 >90%）\n• 具有无缝转换的高效脉冲频率调制 (PFM) / 脉宽调制 (PWM) 模式\n• 极快的瞬态响应：10µs\n• ACB 减小了电感器尺寸要求\n• 抖动以辅助接收频带噪声兼容;
