The TPS6301x 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 1200 mA while using a single-cell Li-Ion or Li-Polymer Battery, and discharge it down to 2.5 V 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 2200 mA. 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 20-pin DSBGA package measuring 2.126 mm × 1.922 mm (YFF).

千萬不要忽略PCB設(shè)計中線寬線距的重要性2023-07-31 22:27
想要做好PCB設(shè)計,除了整體的布線布局外,線寬線距的規(guī)則也非常重要,因為線寬線距決定著電路板的性能和穩(wěn)定性。所以本篇以RK3588為例,詳細(xì)為大家介紹一下PCB線寬線距的通用設(shè)計規(guī)則。要注意的是,布線之前須把軟件默認(rèn)設(shè)置選項設(shè)置好,并打開DRC檢測開關(guān)。布線建議打開5mil格點,等長時可根據(jù)情況設(shè)置1mil格點。PCB布線線寬01布線首先應(yīng)滿足工廠加工能力,1781瀏覽量 -
