  Q GATE ON OFF ON OFF IL A new generation of Linear Technology high voltage synchronous step-down converters, such as the LTВ®3845,
  make it possible to implement positive-to-negative
  conversions for a variety of applications.
  Basic Operation
  Figure 1 shows a simplified block diagram of a positive-tonegative converter. Figure 2 shows an equivalent circuit,
  which helps in understanding the basic operation of the
  circuit in Figure 1. When transistor Q is on (Figure 2a),
  diode D is reverse biased and the current in inductor L …
