The ADP8140 provides high current control of up to four LED drivers. Each driver can sink up to 500 mA. The sink current is programmed for all four drivers with one external resistor.The device features a feedback output that controls an external power supply for optimal efficiency. The ADP8140 also protects the LEDs, power supply, and itself against thermal events, short circuits, overvoltages, and LED open circuits. Multiple ADP8140 ICs are easily connected in parallel to drive additional LED strings or higher current LEDs. The ADP8140 is available in a small, thermally enhanced, lead frame chip scale package (LFCSP).Applications High brightness LED lighting Large format LED backlighting

This application note is to provide users of the UCC2897AEVM with a method of generating acyclic restart or restart attempt of the EVM should the converter encounter an overcurrent condition including an output short.

This single cell Li-Ion battery input boost converter provides a 5.3V output at 1.1A (5.8W). It achieves 90% efficiency at full load and operates at 1MHz. PMP7426 uses the TPS55340 high voltage boost converter.

The UCC3806 is a pin-for-pin-compatible BiCMOS replacement for the UC3846 and UC3856. However this design note explains how some functions in the UCC3806 are programmed differently. In particular the CUR LIM ADJ pin programs the maximum peak current for the current-sense amplifier. This function is completely compatible with that of previous ICs. The second function on this pin is the latch/non-

The LTC6811 is a multicell battery stack monitor that measures up to 12 series connected battery cells with a total measurement error of less than 1.2mV. The cell measurement range of 0V to 5V makes the LTC6811 suitable for most battery chemistries. All 12 cells can be measured in 290?s, and lower data acquisition rates can be selected for high noise reduction.Multiple LTC6811 devices can be connected in series, permitting simultaneous cell monitoring of long, high voltage battery strings. Each LTC6811 has an isoSPI interface for high speed, RF-immune, long distance communications. Using the LTC6811-1, multiple devices are connected in a daisy chain with one host processor connection for all devices. Using the LTC6811-2, multiple devices are connected in parallel to the host processor, with each device individually addressed.The LTC6811 can be powered directly from the battery stack or from an isolated supply. The LTC6811 includes passive balancing for each cell, with individual PWM duty cycle control for each cell. Other features include an onboard 5V regulator, five general purpose I/O lines and a sleep mode, where current consumption is reduced to 4?A.Applications Electric and Hybrid Electric Vehicles Backup Battery Systems Grid Energy Storage High Power Portable Equipment

The AD7175-2 is a low noise, fast settling, multiplexed, 2-/4-channel (fully/pseudo differential) ?-? analog-to-digital converter(ADC) for low bandwidth inputs.
