Abstract This paper proposes a switched-capacitor voltage buck converter (SC-VBC) with variable step-down controller (VSC) and switching frequency (SFC). The VSC SFC change the ratio of SC-VBC in accordance input load current, respectively, enabling to operate efficiently wide-ranging current. Measurements prototype chip demonstrated that our achieved wide range high efficiency 1.3–2.6 V 69%, respectively.

Step-Up Switching-Mode Converter With High Voltage Gain Using a Switched-Capacitor Circuit
A new circuit is proposed for a steep step-up of the line voltage. It integrates a switched-capacitor (SC) circuit within a boost converter. An SC circuit can achieve any voltage ratio, allowing for a boost of the input voltage to high values. It is unregulated to allow for a very high efficiency. The boost stage has a regulation purpose. It can operate at a relatively low duty cycle, thus avoi...
متن کاملA High Efficiency Low-Voltage Soft Switching DC–DC Converter for Portable Applications
This paper presents a novel control method to improve the efficiency of low-voltage DC-DC converters at light loads. Pulse Width Modulation (PWM) converters have poor efficiencies at light loads, while pulse frequency modulation (PFM) control is more efficient for the same cases. Switching losses constitute a major portion of the total power loss at light loads. To decrease the switching losses...

A modeling and analysis of a two-stage multiphase switched-capacitor (MPSC) converter is derived by combining a variable-phase control (VPC) and a pulse-width-modulation (PWM) technique for highefficiency step-up DC-DC conversion. In this MPSC, there are two voltage doublers in series for boosting the voltage gain up to 4 22 = at most. Here, VPC is suggested to realize a variable multiphase ope...

A unified multi-stage power-CMOS-transmission-gate-based quasi-switched-capacitor (QSC) DC-DC converter is proposed to integrate both step-down and step-up modes all in one circuit configuration for low-power applications. In this paper, by using power CMOS transmission gate as a bi-directional switch, the various topologies for step-down and step-up modes can be integrated in the same circuit ...
متن کاملClosed Loop Control of an Interleaved Buck Converter with High Step-Down Conversion Ratio and Low Switch Voltage Stress
Interleaving can be thought of as a method of paralleling converters but it has got additional benefits to offer in addition to those obtained from conventional approaches of paralleling converters. Interleaved converters due to its simple structure and low control complexity are widely used in applications where non-isolation and high output current with low ripples are required. They have got...
