Applications •Battery-powered devices •USB-powered peripherals • Consumer, industrial, medical, automotive: battery-powered or wireline Features • High efficiency at light and maximum loads • Small form factor devices • Ease of design •Cost-effective solutions DC/DC Converters (Switching Regulators) Skyworks’ broad product portfolio includes high-efficiency, pulse width modulation (PWM) switch-mode voltage regulators ideal for a wide variety of applications such as smartphones, portable navigation devices (PNDs), notebook computers, set-top boxes, digital still cameras, and other portable electronic devices. Step-up and step-down converter solutions are available for a range of output power, optimized in both size and performance for specific power levels. The switch-mode products utilize high switching frequencies to minimize output inductor and capacitor size. Internal compensation eliminates the need for additional external components. These products provide optimal light load efficiency and minimum light load ripple. In addition to excellent efficiency, many SwitchReg™ products offer fast turn-on time and fast transient response capabilities. Taking advantage of advanced modular bipolar CMOS DMOS (BCD) processes allows very low resistance switches, and eliminates the need for special packages that require additional thermal relief. An application engineering team is available to assist you and with your design efforts. Application notes and block diagrams are accessible on Skyworks’ Web site: www.skyworksinc.com. High Efficiency Performance Application Diagrams Figures 1 and 2 compare the efficiency performance of a switching regulator with light load mode (LLM), and and with pulse width modulation (PWM) mode only. Figure 1 displays the regulator efficiency with a PWM only mode. Figure 2 displays the regulator efficiency with a LLM. This mode extends the efficiency of the regulator under standby power (light load) conditions, addressing customer demands for longer battery life required in mobile applications. Figures 3 and 4 show step-up (boost) converter and step-down (buck) converter application diagrams.
