Care must be taken not to exceed 1.25V on this input, or the driver may be damaged. A simple analog circuit using two low cost, switching regulators is shown at left. Work- ing from inputs that can range from 15 to 32 VDC,the top regulator (SR1) keeps the input to the LED driver at 12 VDC. The other regulator (SR2), driven off the same input line maintains the control voltage (for the VADJ input) at 5 VDC. The resister network of R1 and R2 can now be used to set the output cur- rent level of the LED driver. This level is equal to: V RR R XV 12 2 ADJ CTRL = + In the second circuit, the 5 VDC regulator (SR2) is replaced by the shunt regulator (D1) circuit connected in parallel with the resistor network. The regulator will maintain the voltage across R2 and R3 at 2.5 VDC, insuring that the 1.25 VDC limit on the VADJ pin will not be exceeded. This circuit will work for inputs between 7VDC and approximately 36 VDC. For inputs between 36 VDC and 60 VDC, a zener diode (D2) has been added. When using the analog control input, the nominal output current is equal to: . II x V 125 NOM MAX ADJ = The VADJ input should be left open if not used. Grounding VADJ will shut the unit down. Connect- ing VADJ to directly to +VIN may damage the unit. Analog Output Current Control (7 - 36 VDC IN) Analog Output Current Control (36 - 60 VDC IN) |
