- Figure 1. An uncomplicated block diagram (a) conceals the TL431's internal complexity, but you need only three external resistors to use the TL431 in a basic shunt-regulator circuit (b)
- Figure 2. An auxiliary winding supplies power to the supply's PWM controller
- Figure 3. In this improved design, pulse-width-controller IC1 derives its power from RT for start-up, auxiliary winding WAUX for normal operation, and shunt-regulator circuit IC2 and Q1 for low-load operation
- Standard precision GNSS module. Datasheet MIA-M10Q
