SWITCHING_REGULATOR_CONVERTER

Published:2009/6/26 4:00:00 Author:May

SWITCHING_REGULATOR_CONVERTER
The Max650 switching regulator produces a regulated 5 V from large negative voltages, such as the -48 V found on telephone lines. The resulting power supply operates with several extemal com-ponents, inclucting a transformer, and it delivers 250 mA. The device includes a 140-V 250-mA pnp transistor, short-circuit protection, and all necessary control circuitry.   (View)

V_F_CONVERTER

Published:2009/6/26 3:56:00 Author:May

V_F_CONVERTER
Voltage developed across Smeter is amplified by 741 opamp having gain of 40 dB so full.scale voltage of 100mV becomes 10V at opamp outptit. This drives modulation input of 555 timer connected as freerunning oscillator. Nominal 1-kHz output increases in frequency as drive current is reduced; conversely, drop in frequency corresponds to stronger signal at S-meter. Developed for use as audible guide when tuning Yagi and other beam antennas for amateur radio operation.-G.Hinkle, Closed Loop Antenna Tuning, 73 Magazine, May 1976, p 32-33.   (View)

SIMPLE_LF_CONVERTER
This converter allows coverage from 25 kHz up to 500 kHz. Use short coax from the converter to receiver antenna input. Tune the receiver to 3.5 MHz, peak for loudest crystal calibrator and tune your receiver higher in frequency to 3.6 MHz and you're tuning the 100 kHz range. 3.7 MHz puts you at 200 kHz, 3.8 MHz equals 300 kHz, 3.9 MHz yields 500 kHz, and 4.0 MHz gives you 500 kHz.   (View)

INDUCTORLESS_POWER_SUPPLY_CONVERTER
Using a 555 timer and voltage doubler, this circuit will supply ≥50mA at 20 Vdc. T1 and T2 act as power amplifiers to drive the voltage doubler. Frequency of operation is approximately 8.5 kHz.   (View)
