ASTRODYNE TDI AWG (Arbitrary Waveform Generator) high-frequency switched-mode power supply post regulator for applications requiring pulse currents with high slew rates, which are currently underserved by typical offline ac-dc converters. Unit can support high pulse currents and peak power, input overhead voltage to overcome lead inductance during pulse rise time and manage repetitive peak semiconductor power and junction temperature to assure long-term reliability. AWG circuit is built around a synchronous buck topology operating at a switching frequency of 200kHz at full load. Converter features a hysteretic control topology, which varies the switching frequency in response to output load changes. Hysteretic control provides optimal availability of input voltage to drive output current rise time.
