4.5V to 28V Input Current-Mode Step-Down Controller with Adjustable Frequency

General Description The MAX8650 synchronous PWM buck controller operates from a 4.5V to 28V input and generates an adjustable 0.7V to 5.5V output voltage at loads up to 25A. The MAX8650 uses a peak current-mode control architecture with an adjustable (200kHz to 1.2MHz) constant switching frequen

Varactor-Tuned Oscillators

Description HP VTO-8000 Series oscillators use a silicon transistor chip as a negative resistance oscillator. The oscillation frequency is determined by a silicon abrupt varactor diode acting as a voltage-variable capacitor in a thin-film micro stripline resonator. This provides extremely fast
