MIC33M356中文资料5.5V, 3A, I2C configurable DC-DC Power Module数据手册Microchip规格书

描述 Description

The MIC33M356 is a high-efficiency, low-voltage input, 3A Continuous current synchronous step-down Power Module. The Constant-ON-Time (COT)control architecture with HyperLight Load™ provides very high efficiency atlight loads, while still having ultra-fast transient response.The I2C interface allows programming the output voltagebetween 0.6V and 1.28V, with 5 mV resolution (-HAYMP and -FAYMP) or between 0.6V and 3.84V, with 10mV and 20 mV resolution (-SAYMP). Two different default voltage options (0.9Vand 1.0V) are provided so that the application can be started with a safevoltage level and then moved to high performance modes under I2Ccontrol. An open-drain Power Good output facilitates outputvoltage monitoring and sequencing. If set in shutdown (EN = GND), the MIC33M356 typically draws 1.5 µA, while the output is discharged through 10 ohm pull-down (if the outputdischarge feature is enabled). The MIC33M356 pinout is compatible with the MIC33M350, sothat applications can be easily converted.The 2.4V to 5.5V input voltage range, low shutdown andquiescent currents make the MIC33M356 ideal for single-cell Li-Ionbattery-powered applications. The 100% duty cycle capability provides lowdropout operation, extending operating range in portable systems. The MIC33M356 is available in a thermally efficient, 24-Lead 3 mm x 4.5 mm x 1.8 mm QFN package, with an operatingjunction temperature range from -40°C to +125°C

简介

MIC33M356属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的MIC33M356稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。
