數字化電源的特點:1.控制智能化它是以數字信號處理器(DSP)或微控制器(MCU)為核心,將數字電源驅動器及PWM控制器作為控制對象而構成的智能化開關電源系統。傳統的由微控制器控制的開關電源,一般只是控制電源的啟動和關斷,并非真正意義的數字電源。2.數模組件組合優化采用“整合數字電源”(Fusion Digital Power)技術,實現了開關電源中模擬組件與數字組件的優化組合。例如,功率級所用的模擬組件MOSFET驅動器,可以很方便地與數字電源控制器相連并實現各種保護及偏置電源管理,而PWM控制器也屬于數控模擬芯片。3.集成度高實現了電源系統單片集成化(Power System on Chip),將大量的分立式元器件整合到一個芯片或一組芯片中。4.控制精度高能充分發揮數字信號處理器及微控制器的優勢,使所設計的數字電源達到高技術指標。例如,其脈寬調制(PWM)分辨力可達150ps(10~12s)的水平,這是傳統開關電源所望塵莫及的。數字電源還能實現多相位控制、非線性控制、負載均流以及故障預測等功能,為研制綠色節能型開關電源提供了便利條件。5.模塊化程度高數字電源模塊化程度高,各模塊之間可以方便地實現有機融合,便于構成分布式數字電源系統,提高電源系統的可靠性。

The PW5300 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.2? powerMOSFET make this regulator highly power efficient. The internal compensation network alsominimizes as much as 6 external component counts. The non-inverting input of error amplifierconnects to a 0.6V precision reference voltage and internal soft-start function can reduce the inrushcurrent. The PW5300 is available in the SOT23-6L package and provides space-saving PCB for theapplication fields

The PW4055 is a complete constant-current /constant-voltage linear charger for single cell lithiumion batteries.Its ThinSOT package and low external component count make the PW4055 ideallysuited for portable applications.Furthermore, the PW4055 is specifically designed to work within USBpower specifications.The PW4055 No external sense resistor is needed, and no blocking diode is required due to theinternal MOSFET architecture.Thermal feedback regulates the charge current to limit the dietemperature during high power operation or high ambient temperature. The charge voltage is fixedat 4.2V, and the charge current can be programmed externally with a single resistor. The PW4055automatically terminates the charge cycle when the charge current drops to 1/10th the programmedvalue after the final float voltage is reached. When the input supply (wall adapter or USB supply) isremoved, the PW4055 automatically enters a low current state, dropping the battery drain currentto less than 2μA. The PW4055 can be put into shutdown mode, reducing the supply current to 25μA.The BAT pin has a 7KV ESD(HBM) capability. Other features include charge current monitor, undervoltage lockout, automatic recharge and a status pin to indicate charge termination and the presenceof an input voltage
