Finally, simulation analysis and experimental test results show that this design of the Buck converter which can achieve the output voltage range from 10 to 300 V continuous adjustability has strong stability and high dynamic response. It can work continuously in 2 hours without exception. ...
The most common switching-power topology is a buck converter, which efficiently transforms high voltages to low voltages. Figure 1shows a typical buck converter in which the N-channel MOSFET, Q1, needs a floating-gate drive signal. The floating-gate drive is part of the PWM (pulse-width-modu...
for acceptable stability margins. The error signal on pin 8 is then forwarded to the comparator and output to drive the power switch. R1 is a current-sense resistor that meters the output current. When the current is unacceptably high, the PWM circuit shuts down, thereby protecting the ...
