Single-Inductor Multi-Output (SIMO) DC-DC Converters With High Light-Load Efficiency and Minimized Cross-Regulation for Portable Devices

Ming-Hsin Huang, +1 more
- 24 Mar 2009 - 
TL;DR: A new delta-voltage generator can automatically switch the operating mode from pulse width modulation (PWM) mode to hysteresis mode, thereby avoiding inductor current accumulation when the total power of the buck output terminals is larger than that of the boost output terminals.
Journal ArticleDOI

Dithering Skip Modulation, Width and Dead Time Controllers in Highly Efficient DC-DC Converters for System-On-Chip Applications

Hong-Wei Huang, +2 more
- 22 Oct 2007 - 
TL;DR: A highly efficient tri-mode DC-DC converter is invented in this paper for system-on-chip (SoC) applications, which is switched to sleeping mode at very light load condition or to high-speed mode at heavy load condition.
Journal ArticleDOI

A Li-Ion Battery Charger With Smooth Control Circuit and Built-In Resistance Compensator for Achieving Stable and Fast Charging

Chia-Hsiang Lin, +2 more
- 01 Feb 2010 - 
TL;DR: A built-in resistance compensator (BRC) technique is presented to speed up the charging time of a lithium-ion battery and the period of the CC stage can be extended to 40% of that of the original design.
Journal ArticleDOI

Hybrid Buck–Boost Feedforward and Reduced Average Inductor Current Techniques in Fast Line Transient and High-Efficiency Buck–Boost Converter

Ping-Ching Huang, +3 more
- 01 Mar 2010 - 
TL;DR: In this article, a buck-boost converter with high efficiency and small output ripple is proposed to extend the battery life of portable devices, and the hybrid buck-Boost feedforward (HBBFF) technique is integrated in this converter to achieve fast line response.
Journal ArticleDOI

A Low Quiescent Current Asynchronous Digital-LDO With PLL-Modulated Fast-DVS Power Management in 40 nm SoC for MIPS Performance Improvement

Yu-Huei Lee, +9 more
- 21 Jan 2013 - 
TL;DR: A low quiescent current asynchronous digital- LDO (D-LDO) regulator integrated with a phase-locked loop (PLL)-modulated switching regulator (SWR) that achieves the near-optimum power management supply for core processor in system-on-chip (SoC).
