Title
Hysteretic Controller For Cmos On-Chip Switching Power Converters
Abstract
The design and implementation of a CMOS analog integrated circuit that provides versatile sliding-mode control laws for high-frequency switching power converters is described. The controller circuit implements general-purpose linear-surface state control laws incorporating compensating dynamics. The analog controller integrated circuit considers current-mode circuit techniques, hence exhibiting good performance as far as operation speed, power consumption, suitability to poorly regulated power supplies and robustness in front of interferences are concerned. The circuit allows modular connection, being composed of externally linearized transconductors based on current conveyors, current-mode amplifiers and filtering stages, and a transimpedance high-speed hysteretic comparator. The. IC includes power MOSFETs and their drivers so that all active elements for implementing a switching power converter are included, only remaining as external components the power reactive elements. Layout details for a a CMOS 0.35mum technology implementation are discussed. The circuit may be used either as a standalone IC controller or as controller circuit that is technology-compatible with on-chip switching power converters and on-chip loads for future powered Systems on Chip.
