DC453B-A

Analog Devices Inc.
The LT1970A is a ?500mA power op amp with precise externally controlled current limiting. Separate control voltages program the sourcing and sinking current limit sense thresholds with 1% accuracy. Output current may be boosted by adding external power transistors.The circuit operates with single or split power supplies from 5V to 36V total supply voltage. In normal operation, the input stage supplies and the output stage supplies are connected (VCC to V+ and VEE to V?). To reduce power dissipation it is possible to power the output stage (V+, V?) from independent, lower voltage rails. The amplifier is unity-gain stable with a 3.6MHz gain-bandwidth product and slews at 1.6V/?s. The LT1970A can drive capacitive and inductive loads directly.Open-collector status flags signal current limit circuit activation, as well as thermal shutdown of the amplifier. An enable logic input puts the amplifier into a low power, high impedance output state when pulled low. Thermal shutdown and a ?800mA fixed current limit protect the chip under fault conditions.The LT1970A is packaged in a 20-lead TSSOP package with a thermally conductive copper bottom plate to facilitate heat sinking.Applications Automatic Test Equipment Laboratory Power Supplies Motor Drivers Thermoelectric Cooler Driver

LT3476EUHF Demo Board | Quad Buck Mode LED Driver, PVIN ≤ 33V, Up to 27VLED @ 350mA or 1.05A

Analog Devices Inc.
Demonstration circuit 976 is a Quadruple High Power LED Driver in Buck Mode featuring the LT3476EUHF. The LT3476 is a quad output, multitopology DC/DC converter designed to operate as a current source for driving high current LEDs. Each of the four regulators on the demo circuit is independently operated. The VIN power supply for the IC ranges from 2.8V to 16V. The PVIN power supply for the buck regulators ranges up to 33V. On the demo circuit, the default current for each output channel is 350mA but it can be adjusted up to 1.05A via resistor dividers at the VADJ pins. The output current should not exceed the rated current of the LEDs used. If 1W LEDs, such as the Lumileds Luxeon LEDs, are used, 350mA current is the maximum. 1A output current is reserved for 3W LEDs, such as Luxeon III. The input voltage is limited by the CAP pin overvoltage protection threshold. As a result, each channel of the demo circuit can drive up to 27V total LED voltage.

DC985A-A/B

Analog Devices Inc.
The LTC4245 Hot Swap? controller allows a board to be safely inserted and removed from a live backplane in multiple supply systems such as CompactPCI and PCI Express. Using four external N-channel pass transistors, the board supply voltages can be ramped up at an adjustable rate and in any desired sequence. An I2C interface and on-board ADC allow monitoring of board current, voltage and fault status for each supply.The device features adjustable dI/dt controlled soft start and foldback limited inrush current. A dual-level timed circuit breaker and fast current limit protect each supply against overcurrent faults. A power good input with timeout allows a downstream supply monitor to disconnect the board supplies. The device can be con?gured to function without a ?12V supply or with an extra 3.3V supply instead of a 5V supply.The controller has additional features to interrupt the host when a fault has occurred, notify when output power is good, detect insertion of a load card and power-up in either the on or off state.Applications Live Board Insertion CompactPCI, CompactPCI Express, CompactTCA, PCI Express Systems
