18650 battery 3.7v 2000mah

　　Low power consumption 18650 battery 3.7v 2000mah powered boost circuit diagram

　　In portable electronic devices (typically such as MP3 players), only 1 or 2 batteries are often used for power supply. In this circuit system, it is essential to use an integrated circuit or LCD power supply with a working power supply of 5V. , the most applicable method is to use a boost IC.

　　The RH5RH/5RI series (product of Ricoh Corporation of Japan) is a dedicated fixed-output switching regulator IC for boosting. It only needs three external components: an inductor, a diode and a capacitor to obtain a fixed boost output. The best feature of this circuit is that it consumes very little power (4~15uA) and can still work normally even at a low input voltage of 0.9V.

　　The RH5RI and RH5RH series are frequency modulation (pFM) and pulse width modulation (pWM) three-terminal boost switching regulator ICs respectively. It has two types: the RH5RIxx1 (RH5RHxx1) series with a driver included in the IC chip and the RH5RIxx2 (RH5RHxx2) series with an external driver. The former is suitable for circuits with load changes from no load to several mA; while the latter is suitable for circuits with load changes from several mA to hundreds of mA.

　　The RH5RH/5RI series IC is characterized by low power consumption. The power consumption is only 4~15uA when no-load. The starting operating voltage is only 0.9V. The efficiency is greater than 80%. It adopts SOT-89 small chip package.
