PLL-based converter controls light source - EDN Design Ideas: July 2, 1998 [ NOTE: FILE
has multiple design, scroll for this one.] Using the circuit in Figure 1, you can digitally control the light intensity of a lamp. The control loop is based on a PLL, in which the VCO comprises a light-to-frequency converter (TSL220) coupled to a light source that derives its drive from a switching regulator (L4970A). The output of the phase/frequency comparator (4046) serves as the control voltage for the switching regulator. The control voltage is proportional to the frequency error between the reference frequency (fREF) and the signal frequency (fiN) coming from the light-to-frequency converter.
