Switching Regulators Replac 1-A Linears
Pin-compatible with 78xx linear regulators, V-Infinity’s V78XX-1000 series of 1-A switching regulators deliver efficiencies of up to 95%
SMT Power Inductors Feature High Saturation Levels
The PG0702NL from Pulse is a series of flat-coil surface mount power inductors that feature high saturation current levels, tight DCR tolerance, low thermal aging, and low cost
High-Temperature Supercaps Target Portable Devices
Tecate Industries, the CAP-XX H series supercapacitors feature a high-temperature electrolyte that extends both the operating voltage (from 4.5 V to 5.5 V), and the max operating temperature (from 75°C to 85°C)
Boost Controller Supports Industrial LED Lighting
With its wide, 4.5-V to 52-V voltage range, Texas Instruments’ TPS40211 nonsynchronous boost controller enables designers to efficiently manage LED lighting, industrial control and battery-powered systems. The chip is capable of driving 1-W to 5-W high-brightness LEDs
PWM Controller Creates Scalable Designs
Intersil’s ISL8120 dual-output or variable-phase PWM controller combines a wide input- voltage range, current sharing and variable phase shifting to create a highly scalable controller design
