Synchronous buck regulators

25 July 2012 Power Electronics / Power Management

International Rectifier has introduced its third generation of SupIRBuck synchronous buck voltage regulators. The new single-output devices feature a newly patented modulator scheme claimed to generate the industry’s smallest, jitter-free pulse widths. By reducing jitter for pulse widths as small as 50 ns, the technology enables higher closed-loop bandwidth for better transient response and lower output capacitance. In addition to switching frequency up to 1,5 MHz, pre-biased startup, input voltage aware enable, tracking and programmable power-good, the new devices offer reference voltage accuracy of 0,5%, enhanced line/load regulation with input voltage feed-forward and thermal compensation for current limit.
