LINEAR LTC1591/LTC1597 DATA SHEET
LTC1591/LTC1597 are 5V single supply 14-bit and 16-bit parallel input multiplying current output DACs. Their INL and DNL are accurate to 1LSB over the industrial temperature range in both 2 and 4 quadrant multiplying modes. True 16-bit 4 quadrant multiplication is achieved with on-chip 4 quadrant multiplication resistors. These DACs also include an internal deglitcher circuit which reduces the glitch impulse to less than 2nV-s (typ). The asynchronous CLR pin resets the LTC1591/LTC1597 to zero scale and LTC1591-1/LTC1597-1 to midscale. LTC1591/LTC1597 are available in 28-pin SSOP and PDIP packages and are specified over the industrial temperature range. For serial interface 16-bit current output DACs, refer to the LTC1595/LTC1596 data sheet.

LINEAR TECHNOLOGY - LT1942 handbook
The LT1942 is a highly integrated quad switching regulator designed to provide all necessary power supply functions for TFT displays, including the white LED backlight driver. The TFT supply incorporates two boost and one inverting DC/DC converters. The TFT supply output voltages are independently set, unlike charge pump solutions which have many limitations. Power sequencing for the TFT supply is built into the part and is user programmable. The LED driver is a boost DC/DC converter that can be independently controlled. The LED driver has built-in dimming control for precise control of LED current. An 8:1 dimming range is achieved by adjusting the CTRL4 voltage.The user can elect to drive a single string or two strings of LEDs. An LED ballast circuit is included to precisely match the LED currents if two strings of LEDs are used. Soft-start is built into the LED driver as well as the primary TFT supply. The LT1942 is available in a low profile (0.75mm) 24-lead QFN (4mm × 4mm) package.
LINEAR TECHNOLOGY - LT3496 handbook
The LT3496 is a triple output DC/DC converter designed to operate as a constant-current source and is ideal for driving LEDs. The LT3496 works in buck, boost or buck-boost mode. The LT3496 uses a fixed frequency, current mode architecture resulting in stable operation over a wide range of supply and output voltages. A frequency adjust pin allows the user to program switching frequency between 330kHz and 2.1MHz to optimize efficiency and external component size. The LT3496 supports 3000:1 dimming control on each channel. Each of the three regulators is independently operated by that channel’s PWM signal. The PWM feature allows precise adjustment of the color mixing or dimming ratio of the LED source. Each of the three channels has a built-in gate driver to drive an external LED-disconnect P-channel MOSFET, allowing high dimming range. The output current range of each channel of the LT3496 is programmed with an external sense resistor. The CTRL pin is used to adjust the LED current either for analog dimming or overtemperature protection.
