TPS6302x是TI 公司的高效小型升降壓電源解決方案,輸入電壓從1.8V到5.5V,輸出電流可高達3A,固定和可調輸出電壓從1.2V到5.5V,效率高達96%,能在降壓和升壓模式自動轉換,靜態電流小于50uA,固定工作頻率2.4MHz,可用于所有兩節和三節堿性電池, NiCd 或NiMH或單節鋰電池供電的設備,超小型移動PC和MID,數碼媒體播放器,DSC和攝像機.本文介紹了TPS6302x主要特性,方框圖, 可調輸出電壓典型應用電路圖以及TPS63020EVM評估板特性,電路圖和材料清單(BOM).
The TPS6302x devices provide a power supply solution for products powered by either a two-cell or three-cell alkaline, NiCd or NiMH battery, or a one-cell Li-Ion or Li-polymer battery. Output currents can go as high as 3A while using a single-cell Li-Ion or Li-Polymer Battery, and discharge it down to 2.5V or lower. The buck-boost converter is based on a fixed frequency, pulse-width-
modulation (PWM) controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters Power Save mode to maintain high efficiency over a wide load current range. The Power Save mode can be disabled, forcing the converter to operate at a fixed switching frequency. The maximum average current in the switches is limited to a typical value of 4A. The output voltage is programmable using an external resistor divider, or is fixed internally on the chip. The converter can be disabled to minimize battery drain. During shutdown, the load is disconnected from the battery. The device is packaged in a 14-pin QFN PowerPAD packagemeasuring 3 × 4 mm (DSJ).TPS63020主要特性:
