Application of DC-DC Converter in Sensor and MEMS Device Integration and Packaging

DC-DC (direct current controlled direct current) converter is the core control circuit in field of power electronics technology. Based on theory sensors and MEMS (microelectromechanical systems), this paper constructs a device integration packaging model proposes an enhanced equalization technology with offset correction function suitable for two-phase converters. Aiming at generation mechanism output ripple converter, adopts elimination based interleaved synchronous clock self-calibration time generator, so that each phase accurately staggered within full-load range, problem amplitude solved. During simulation process, high-performance chip designed implemented, which includes adaptive on-time logic feedback, self-calibrating zero-current turn-off circuit, robust switch transistor drive logic. The experimental results show reaches 6A, peak efficiency 91%, phase-to-phase error <0.6%, <9 mV. In 90.265 V AC input, 0-10 W load voltage less than 0.96%, when switched between no-load full-load, system response speed 200 ps, effectively improves overall performance converter.
