Dual-Synchronous Buck Controllers for Point-of-Load, Tracking, and DDR Memory Power Supplies

General Description The MAX8537/MAX8539 controllers provide a complete power-management solution for both double-data-rate (DDR) and combiner supplies. The MAX8537 and MAX8539 are configured for out-of-phase and in-phase DDR power-supply operations, respectively, and generate three outputs: the m

PLASTIC ENCAPSULATED DEVICES

[MAXIM INTEGRATED PRODUCTS] Device Description General The MAX8538 is configured as a dual out-of-phase controller for point-of-load supplies. Each buck controller can source or sink up to 25A of current, while the termination reference can supply up to 15mA output. The MAX8538 uses constant-f

双路同步buck控制器，用于负载点、跟踪和DDR存储器供电

MAX8537/MAX8539控制器为双数据速率(DDR)和组合器电源提供了一个完整的电源管理方案。MAX8537和MAX8539分别配置为反相和同相DDR电源工作模式，产生三个输出：主存储器电压(VDDQ)、跟踪吸收/供出终结电压(VTT)和终结参考电压(VTTR)。MAX8538配置为双组反相控制器，适用于负载点电源。每个buck控制器能够供出和吸收高达25A电流，终结基准能够提供15mA输出。\n\n MAX8537/MAX8538/MAX8539使用恒定频率电压模式结构，工作频率为200kHz至1.4MHz。内部高带宽(25MHz)运放用作误差放大器调节输出电压。提供快速瞬态 • MAX8537/MAX8539：完整的DDR电源\n• MAX8538：双路非跟踪控制器\n• 反相(MAX8537/MAX8538)或者同相(MAX8539)工作\n• 4.5V至23V宽输入范围(外加5V电源时可工作于最低至1.8V输入)\n• 跟踪电源保证VTT = VTTR = 1/2 VDDQ\n• 可调输出从0.8V至3.6V，1%精度\n• VTTR参考可供出和吸收高达15mA\n• 200kHz至1.4MHz可调开关频率\n• 全陶瓷设计\n• 效率>90%\n• 单独的 POK_和EN_\n• 每个输出具有可调的软启动和软关断\n• 无损、可调节、打嗝式电;
