===== Projects/ ===== ==== Constant Current Sink Board ==== * Constant Current Board * This board is useful in Hi-Fi amplifier systems where a constant current sink is required. The 10M45S IC is capable of handling up to 450v, and a heatsink is definitely necessary. The 10M45S can be substituted for 'DN2540N5'. I am currently proposing to use it in my 6as7 Parallel Single Ended, Dual Mono Amplifiers; they will be placed on the cathode to ground, replacing the 1k/10W resistors. * **Rset** resistor value is calculated with this formula: **Rset** = 1.25/**Iout**. **Iout** being the current you wish to set. ---- * {{ :projects:10m45s-ccs.fzz |CCS (Fritzing File)}} * {{:projects:10m45s-ccs_pcb.jpg?200|}} * {{:projects:10m45s-ccs_schem.jpg?200|}}
