A 5 A 100 kHz monolithic bipolar DC/DC converter

摘要

The authors describe a new monolithic switching regulator, aimed at flyback and boost converter applications. The IC provides all the necessary circuitry to form a complete switching regulator. It can be used in any topology requiring a 5 A, 100 kHz, low-side, output switch. Current-mode control is used to provide a fast response and wide dynamic range regulator. A new adaptive blanking circuit allows the IC to ignore switch current turn-on spikes, while extending the control range of the regulator.
