Abstract
One or more embodiments relate to a circuit that can be used to prevent cross conduction in an SMPS including multiple half-bridge modules connected in parallel to a single output inductor and driven by a single pulse width modulation (PWM) signal. According to certain aspects, each high-side driver and low-side driver in a single half-bridge module is synchronized in their switching with corresponding high-side drivers and low-side drivers in other half-bridge modules.
