The output voltage of the converters of Fig. 6 is ... The SEPIC converter is also one of the potential dc-dc converters for LED lighting. Fig. 7 shows the
CS5171 - Boost Regulators, 1.5 A, 280 kHz/560 kHz
www.onsemi.comregulators with a high efficiency, 1.5 A integrated switch. These parts operate over a wide input voltage range, from 2.7 V to 30 V. The flexibility of the design allows the chips to operate in most power supply configurations, including boost, flyback, forward, inverting, and SEPIC. The ICs utilize current mode architecture, which allows
Designing DC/DC converters based on ZETA topology
www.ti.comUnlike the SEPIC converter, which is configured with a standard boost converter, the ZETA converter is config-ured from a buck controller that drives a high-side L1aPMOS FET. The ZETA converter is another option for regulating an unregulated input-power supply, like a low-cost wall wart. To minimize board space, a coupled inductor can be used.
Creating a Negative Output Voltage Using a Buck Converter
www.vishay.comtopology or possibly a SEPIC converter, both of which offer reasonable efficiency that is much higher than a linear regulator. However, the same outcome can be reached with a buck converter. With a slight alteration to the nodal references of a synchronous buck converter, we can create a negative boost converter, as shown in Fig. 1. Fig. 1
