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.
It works in 16 measuring modes, one generating and calibrating mode.
The UFDC-1 allows designers to embed frequency-to-digital conversion into smart sensors.
Features include: a frequency range from 0.05Hz to 7.5MHz (120MHz with prescaling); programmable accuracy from 1 to 0.001%; nonredundant conversion time; quartz-accurate automated calibration; RS232, SPI and I2C interfaces; master and slave communication modes; single power supply 4.5-5.5V; current consumption at 16MHz, 5V, 25C of less than 20mA; an operating temperature range from -40 to +85C; and a 28-lead plastic dual inline package.
Custom designs are also available.
The UFDC-1 can be used for any frequency-time domain signal like a standard ADC for the analogue signal domain.
Now sensors manufacturers will be able simply integrate the UFDC-1 in microsystems and digital sensors in order to produce a serial output or bus capability and to target at a cost-driven industrial market.
The device's applications are numerous: from DAQ systems, measuring instruments (frequency counters, tachometers, DMM) and quasidigital sensors up to one-chip digital sensors design, smart (self-adaptive) sensors and multifunction sensors and systems.
