A buck converter with adaptive on-time PFM control and adjustable output voltage
Hyunseok Nam, Youngkook Ahn and Jeongjin Roh
Abstract
This letter proposes a new adaptive on-time pulse-frequency modulation (PFM) circuit that operates at a wide range of supply voltage levels and that can generate various output voltage levels compared to conventional circuits. The circuit’s peak inductor current is well-controlled; the magnitude of the output ripple voltage is constant, even when the supply and output voltage levels are significantly different. Since the ripple voltage is a noise component, constant ripple voltage is important for predictable noise of a power management system.
