Title:
負荷制御回路
Document Type and Number:
Japanese Patent JP4348241
Kind Code:
B2
Abstract:
A load control circuit enabling miniaturization of a brightness adjustment system. The load control circuit includes a variable resistor for generating a reference potential. A first duty signal generation circuit connected to the variable resistor controls a LED based on a reference potential. A second duty signal generation circuit connected to the variable resistor generates a second duty signal controls a lamp. The first duty signal generation circuit is configured so that the first duty signal changes differently from the second duty signal.
