At a recent industry meet in New Delhi and Bangalore, Intersil presented salient features of its power and analog solutions.
Richard Garcia, Principal Applications Engineer, Power Management Products, outlined the unique features of Intersil power solutions for LED lighting and LCD display. These solutions cover a wide range of AC line voltages from 80V to 260V, while delivering full solutions for LCD display power. Offline LED drivers have high power factor and low current harmonic distortion even without PFC controller.
While speaking on isolated power solutions for industrial applications, Garcia observed that Intersil delivers a complete range of PWM controllers and bridge drivers for single- and double-ended isolated DC/DC converters. The Company, he said, offers the full power management solutions for telecom and industrial applications. Garcia added that Intersil’s IC technologies “can deliver the smallest packaging with the highest performance”, making these ideal for industrial and telecom applications.
Garcia also spoke on power management in general purpose applications. He said that Intersil “provided complete power management solutions to control, process, and monitor power to ensure proper operation of general purpose products”. Among the general purpose products he elaborated on were the blood glucose monitor, industrial control system, and DSLAM power regulation system. While speaking on the importance of hot-plug—an interface between the power and the load, and without which the low impedance capacitor filters on the pluggable board create a temporary short circuit to the backplane power bus—he noted that Intersil “provides a full family of high performance hot-plug controllers”.
While discussing power management solutions for handheld products, Garcia pointed out that “Intersil provides the right solutions for multi-cell battery protection requirements”. Such solutions, he said, provide support for up to 12 cells in series. The Company also provides amplifiers and motor drivers to make up the entire system.
Intersil’s Tamara Schmitz, while speaking on operational amplifier topologies and applications, gave a summary of various Intersil amplifier products, including voltage feedback amplifiers for low cost general applications; rail-to-rail amplifiers for low voltage handheld devices; low noise amplifiers for ultrasound, communications, and medical equipment; precision rail-to-rail input and output amplifiers for handheld devices, sensors, transducers, and instrumentation; current feedback amplifiers for video, ADSL, and communications; and a slew of enhanced amplifiers for general purpose and communications systems.
Schmitz commented that the rail-to-rail low power voltage mode feedback amplifier is “the answer to the industry trend to lower and lower power supplies”.
While addressing Intersil’s solutions for high-speed signal transmission, Schmitz elaborated on video transmission. Among the products she touched on were Intersil’s differential equalizers EL9111 and EL9112, which are triple channel differential receiver and equalizer, and EL9110, which is a single channel differential receiver and equalizer. The Company, she said, will also be introducing shorter reach equalizers: ISL59913 and ISL59910.
Schmidt also discussed light sensors and instrumentation solutions. She said, “Intersil is the leader in ambient light sensor solutions.” She also claimed that the Company’s ISL29015 is the “world’s first fully integrated light sensor plus proximity sensor”.
