SERIAL-PARALLEL DRIVE CIRCUIT DEVICE AND A METHOD FOR DRIVING A SERIAL-PARALLEL DRIVE CIRCUIT, CAPABLE OF MINIMIZING CAPACITY OF A POWER SUPPLY UNIT

摘要

PURPOSE: A serial-parallel drive circuit device and a method for driving a serial-parallel drive circuit are provided to reduce a manufacturing cost by driving loads according to a size of a resistance without using a switch stepwise.;CONSTITUTION: A serial-parallel drive circuit device includes a serial-parallel drive circuit unit(210) and a controller(220). A serial-parallel drive circuit unit drives n loads(230). The serial-parallel drive circuit unit includes a plurality of p type power supply units and a plurality of n type power supply units. The polarity of the output of the p type power supply units is positive. The polarity of the output of the n type power supply units is negative. The controller supplies a control signal to the p type power supply units and the n type power supply units according to the size of n loads.;COPYRIGHT KIPO 2010
