About

Invention The voltage-mode controlled buck converter is an extremely effective invention with less chip area, less number of components, high accuracy and efficiency. Unlike the conventional compensator, the Differential Difference Amplifier (DDA) based compensator achieves overall 60% reduction in chip area. With the addition of high accuracy delay-compensated ramp generator, the system is not only operating at normal converter frequency (~1MHz) and also at very high frequency (VHF) range even using low-speed comparators.  As it is a simplified architecture, it can be implemented on chip with less development cost. Marketing Opportunity In present time, the devices like smart phones, notebook computers; home appliances etc. needs a switching regulator to regulate the voltage source to a suitable voltage. The proposed voltage-mode controlled buck converter is very effective from the marketing point of view, due to less number of components and reduced chip area, the overall product cost is decreased. And nowadays, all the devices need the power management solution, so the chip is technically designed to perfection regarding efficiency and accuracy to handle the power consumption problem. Key Benefits 60% reduction in chip area of the compensator Less number of components and reduced chip area, decrease overall die cost and product cost High accuracy delay-compensated low power ramp generator Simple but effective design and hence short time-to-market
