Dynamic/static signal converting circuit and method for use in a lamp driving device

摘要

A dynamic/static signal converting circuit and method for use in a lamp driving device has a clock delay unit for delaying a system clock signal for a predetermined period of time; a converting unit for receiving a dynamic signal for driving an LED, synchronizing the dynamic signal with a delayed system clock signal and then converting the dynamic signal into a static signal; and an LED driving unit for driving the LED in response to the static signal output from the converting unit.
