App Guide for Flat-Panel TV Sets
Your partner for flat-panel TV sets NXP Semiconductors offers a wide portfolio of advanced solutions for flat-panel TV sets. All are built on our deep understanding of the needs of set designers and manufacturers, and of market requirements. We can deliver application-specific solutions for reception, drawing on a complete range of silicon tuners that cover all the major standards for hybrid terrestrial, cable and satellite reception. We also support peripheral functions, such as advanced audio and HDMI interfaces, and provide an extensive portfolio of standard products for TVs. We use next-generation packaging to save space, lower costs, and improve AV content security, and we reduce energy consumption with low-power technologies that dramatically increase efficiency. We design for ruggedness, supplying devices that stand up to intensive use, and we deliver the high integration needed to simplify development, lower BOM and production costs, and reduce time-to-market. We are known for innovation and our ability to introduce new technologies that set the standard for performance, efficiency, and size. Our new chip-scale package (CSP) devices, for example, have an exceptionally compact footprint yet achieve a new benchmark in mechanical robustness. We support our customers with a cost-efficient supply chain, and an enterprise-wide commitment to the highest standards of security, quality, and reliability. We also help our customers prepare for the future, by working with them to implement new features, such as 3D, that will drive growth. In short, our customers have the confidence that comes from working with a world-class partner.
Primary AC/DC controllers <75 W flyback controller TEA1738 for primary control of small flat-panel TVs The TEA1738 supports high-end regulation schemes. For designs that need less sophisticated flyback control, the TEA1733 is recommended. Features:
SMPS controller IC enabling low-cost applications
Large input voltage range (12 to 30 V)
Integrated OverVoltage Protection (OVP) on pin VCC
Very low supply current during start-up and restart (typically 10 μA)
Low supply current during normal operation (typically 0.55 mA without load)
Overpower or high/low line compensation
Adjustable overpower time-out
Adjustable overpower restart timer
Fixed switching frequency with frequency jitter to reduce EMI
Frequency reduction at medium power operation to maintain high efficiency
Frequency reduction with fixed minimum peak current
Frequency increase at peak power operation
Slope compensation for CCM operation
Low and adjustable OverCurrent Protection (OCP) trip level
Adjustable soft-start operation
Two protection inputs (e.g. for input UVP and OVP, OTP and output OVP)
IC overtemperature protection
Silicon tuners Our portfolio supports compatibility with legacy transmission formats, by covering hybrid analog and digital terrestrial reception. We also support the latest digital standards, along with cable and free-to-air satellite reception. We offer the high performance required by TV set manufacturers, and our software drivers simplify design work even further. All our tuners deliver excellent performance and are suitable for high-end analog/digital applications. Also, our products have been validated against major standards worldwide.
