This article presents a scalable multiphase peak current-mode Buck controller with sub-milliohm direct current resistance (DCR) current sensing and synchronized overcurrent protection. Low DCR current sensing capability is critical in pursuing high e

This paper proposes a low direct current resistance (DCR) current sensing scheme for multiphase peak current mode controller. A second order RC sensing network amplifies the high frequency sensing signal and also extracts the low frequency signal. Th

This paper proposes a robust hiccup mode over current protection scheme for decentralized current mode multiphase DC-DC converters. The current comparator for pulse width modulation is reused for peak current limiting. The latch-up issue in multiphas

Inductors with ultra-low DC resistance (DCR) are preferred in DC-DC converters due to low power loss and high efficiency. Previous lossless DCR current sensing method suffers from bad current readback accuracy for ulta-low DCR inductors, due to leaka

In order to incorporate the advantage of the $V^{2}$ control scheme and the benefits of digital implementation, this paper proposes a digital $V^{2}$ control with hybrid capacitor current ramp compensation, which includes the estimated output capacit

Constant on-time $V^{2}$ control for point-of-load buck converters has instability issues in the cases that the output capacitors' RC time constants are small. This paper intensively studies the proposed solution using capacitor current ramp compensa

$V^{2}$ control has advantages of simple implementation and fast transient response and is widely used in industry for point-of-load applications. This control scheme is elegant when output capacitors with large RC time constant are employed, such as
The conventional slope compensations for current mode controls do not take all the parameters’ changes into account, so the variations on small-signal transfer functions limit the voltage loop bandwidth (BW). In order to optimize the dynamic perfor
