高效率、5路输出、主电源控制器，用于笔记本电脑

MAX1533/MAX1537是两路降压型，同步整流的开关电源(SMPS)控制器，用于在电池供电系统中产生主5V/3.3V电源。在最低至最高26V的电压输入范围内，优化的交错固定频率工作模式将输入纹波电流降至最低。优化的40/60交错控制使输入电压能够在占空比交迭前降至8.3V，而使用180°异相稳压器，输入降至10V时，便出现占空比交迭。输出电流检测使用检流电阻实现精确的电流限制。此外，可以采用无损电感检流以降低功耗。\n 内部5V和3.3V线性稳压器为MAX1533/MAX1537和栅极驱动器，以及外部活动负载供电，最大电流100mA。当主PWM稳压器工作时，自动自举开关将内部线性稳压器旁 \n• 固定频率，电流模式控制 \n• 40/60优化交错 \n• 精确差分检流输入 \n• 具有100mA带载能力的内部5V和3.3V线性稳压器 \n• 辅助12V或可调150mA线性稳压器(仅对MAX1537) \n• Dual Mode™反馈—3.3V/5V固定或可调输出(双模)电压 \n• 200kHz/300kHz/500kHz开关频率 \n• 通用上电顺序控制 \n• 可调过压和欠压保护 \n• 6V至26V输入范围 \n• 2V ±0.75%基准输出 \n• 电源就绪输出 \n• 软关断 \n• 5µA (典型值)关断电流;
