TDA2030AH driver

Description

The TDA2030AH is a monolithic IC in Pentawatt package intended for use as low frequency class AB amplifier. With VS max = 44V it is particularly suited for more reliable applications without regulated supply and for 35W driver circuits using low-cost complementary pairs.

The TDA2030A provides high output current and has very low harmonic and cross-over distortion. Further the device incorporates a short circuit protection system comprising an arrangement for automatically limiting the dissipated power so as to keep the working point of the output transistors within their safe operating area. A conventional thermal shut-down system is also included.

MULTIWAY SPEAKER SYSTEMS AND ACTIVE  BOXES

Multiway loudspeaker systems provide the best possible acoustic performance since each loudspeaker is specially designed and optimized to handle a limited range of frequencies. Commonly, these loudspeaker systems divide the audio spectrum into two or three bands.

OZ9902 datasheet

Description

The OZ9902 is a dual, high power LED driver designed to build LED backlight for largesize LCD TV applications. It integrates two independently-controlled LED drivers to achieve optimum effi ciency. The drive outputs are phase-shifted by 180 degrees to minimize current ripple in high power applications.

0Z9902 supports independent Pulse Width Modulation (PWM) dimming control for each channel and common analog dimming control for both channels. It provides system design fl exibility for LCD TV with local dimming or 3D display mode. […]

Applications

• LCD Monitor
• LCD TV
