The buck converter circuit is composed of LM305. It uses self-excited buck DC / DC converter. Input voltage is +12 ~ +30 V, output voltage is +5 V, maximum output current is 2A. The internal LM3O5 is a robot control integrated circuit composed of a reference voltage, operational amplifiers, driver circuit. Output voltage is set to 3V or less. It can not be switching. The loss of VT increases. Output voltage U. = [(R1 + R2/R2] UREF, UREF = 1.8V.
