چکیده
Abstract In this paper, we describe a CMOS DC-DC converter with a variable output voltage (8-12V @100mA) for a portable battery-operated system applications. The proposed DC-DC converter is used along with a Pulse-Frequency Modulation (PFM) method and consists of a reference circuit, a feedback resistor, a controller, and an internal oscillator. The integrated DC-DC converter with two external passive components(L,C) has been designed and fabricated on a 0.6 μm 2-poly, 3-metal CMOS process and could be applied to the Personal Digital Assistants(PDA), Cellular Phone, Laptop Computer, etc. Keyword DC-DC converter,portable system,PFM

A 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...

Abstract -This paper presents an optimum design for low-voltage, low-power DC-DC converter which has a controller and integrated CMOS switches using small size inductor (luH). Optimum design for single chip DC/DC converter is achieved by analyzing the amount of conduction and switching losses. Through the loss analyses, it is turned out that a constant frequency hard switching PWM converter wit...

متن کاملA Buck-Boost Hybrid DC-DC Converter for Wearable Health Monitoring Devices
A hybrid approach of the DC-DC conversion is presented for battery-operated portable electronics systems such as wearable health monitoring devices. A switched-capacitor (SC) DC-DC converter is steered by hysteretic control to provide buck-boost conversion with a flexible conversion ratio, and its output is regulated by a low-drop-out (LDO) regulator delivering a low-ripple DC output. The SC DC...
