Filed: 2000-07-25
Abstract: PURPOSE: A dimming control circuit for an inverter is provided to minimize a lamp brightness abrupt variation after changing an analog operation range to a PWM(pulse width modulation) operation range by performing a linear operation to a brightness variation of an input dimming variation with a hybrid dimming method having an analog dimming and PWM dimming. CONSTITUTION: A switching part(Q3) transmits an input voltage(Vin) to a lamp(LAMP). On/Off controller(11) is turned on/off by an on/off signal, and determines whether a power is supplied to the lamp or not. If an input dimming is linear-varied and transmitted in case of the lamp-on, a dimming controller generates a predetermined reference voltage, varies an input terminal of the next stage within an analog operation range, and fixes it in PWM operation range. Amplifier(13) receives a reference voltage of the dimming controller and a feedback value of an output terminal, compares the reference voltage with the feedback value, and outputs the comparing result. A first comparator(14) receives an output signal of the amplifier(13), compares it with another value from another input terminal, and outputs the comparing result. An output driver receives an output signal of the first comparator(14), and performs a duty control of the switching part(Q3). An oscillator(16) generates a comparing value about a reference voltage of the dimming controller in order to discriminate between the analog operation range and the PWM operation range. A second comparator compares the comparing value of the oscillator(16) and the reference voltage of the dimming controller, and turns on/off the output driver according to the comparing result. A protective circuit(18) maintains an output voltage in case of the lamp-on, and protects a system.
