Driver drives LED efficiency
STMicroelectronics has introduced a new white LED driver with specific features for small LCD module backlight and high efficiency white LED power supply for portable applications.
Single-chip tuner cuts set-top box parts count
The STB6000 single-chip silicon tuner is designed to replace complex discrete component tuners in set-top boxes used for receiving digital TV or web-based material via satellite.
This saves space and costs for manufacturers of portable products, while delivering stereo FM R(B)DS reception (RX) direct to Bluetooth headsets.
The integrated short-range FM R(B)DS transmitter (TX) allows users to enjoy stored music content on any in-car or home FM radio tuner and delivers increased versatility to the mobile device.
This new chip from ST is manufactured in ST's advanced low-leakage ultra-low-power 65nm RFCMOS technology.
The STLC2690 is compliant with BT v2.1+EDR and further increases the class-1.5 Bluetooth output power, requiring only one supply voltage and without any calibration in production.
The Bluetooth link stability is dramatically increased by further improving the Bluetooth receiver sensitivity, while reducing the current consumption by up to 35% compared to previous 130nm products.
Real-time programmable filters for optimum search and sensitivity stability allow the STLC2690 to be used with integrated FM antennas.
The device supports all deployed R(B)DS services and all worldwide FM bands (65 to 108MHz).
The short-range FM transmitter is specifically designed for use in mobile phones that also take advantage of the presence of a FM receiver.
SureTune technology automatically selects the optimal FM transmit frequency, while the programmable high-output power allows stable operation even when using integrated antennas with poor efficiency.
The STLC2690 delivers a stable and user-friendly FM transmission implementation with real enhancement of the user experience in mobile applications.
The STLC2690 comes in a wafer level chip scale package (WLCSP) with a 0.4mm pitch.
Its low external BOM count allows a PCB footprint as small as 36mm2.
The pin-out arrangement of the STLC2690 is also suitable for use on low-cost PCB assemblies.
