By adding another diode and capacitor we can generate negative output voltages as shown in figure 5. Good for bringing solar lights back to life. Back to home page. Sadly I forgot to make note which these where. Features of the CL type LED driver detect voltage on the solar cell, optional control the charging process and prevent the reversely charging from battery to solar cell etc; detecting status of battery, producing KHz pulse-train, being in standby mode manually and limiting the peak driving current etc. It requires only an external inductor to construct a boost power supply with over 90 per cent efficiency. In figure 6 we have configured the HPHL as a 1:
