EE 212L: Voltage Conversion
Pre-lab:
- Review data sheets for regulator and DC-DC converter, and note
key characteristics such as range for input voltages, range for output
currents, rated output voltages, dropout voltages, etc.
- Design the voltage divider requested for Task 1 below giving
some thought to the impact of the load resistor, resistor values and
the fact that we have 1/4W resistors available in the part bins.
Objective: Characterize methods of generating DC voltages of
desired values from a fixed (here 12V) source.
Tasks:
- 12V to 5V via voltage division (generate v-i curve using varied,
but safe values for load resistor)
- 12V to 5V via linear regulator (note specifications; generate
v-i curve using varied, but safe values for load resistor)
- 12V to +15V and -15V via DC-to-DC converter (note specifications
and application notes; generate v-i curve using varied, but safe
values for load resistor)
- Compare the three approaches investigated above, i.e., when
would they be appropriate to use, advantages, disadvantages,
etc.
