(免费)Simple Techniques to Generate a Negative Voltage Bias Supply

tony155

Developing a low power negative supply voltage
from a positive input supply can be accomplished
using some very common PWM control ICs. Typical
applications include generating a negative five
through twelve volt (-5V to -12V) supply for analog
function ICs (OP amps), RS-232 communication
circuits, and MOSFET or IGBT gate drives at power
levels below a few Watts.
