51. Use Current to Drive Solenoid, Relay from Array of Voltages
    Drivers Texas Instruments DRV110 DRV120
    James Lockridge, Texas Instruments Electronic Design Rather than use a fixed-rail voltage source, it’s more efficient and flexible to utilize a current source so that performance remains consistent while supply rail and coil resistance ...

52. Circuit Ensures Smooth "Soft Start" for Isolated Converter, Limits In-Rush Current
    Supply Texas Instruments LM5025
    Mangjing Xie Electronic Design Isolated dc-dc converters are prone to excessive in-rush current, but a small soft-start circuit can solve the problem and limit that current. Most dc-dc converters require a soft-start circuit to limit the in-rush ...

53. Make sure your optocoupler is properly biased
    Optoelectronics Supply Texas Instruments TL431 UCC2897A
    Brian King, Texas Instruments EDN In isolated power supplies, optocouplers pass the feedback signal across the isolation boundary. Optocouplers contain both a light-emitting diode (LED) and a photo detector. Current flowing through the LED results ...
