The LTC3773 is a high performance, 3-phase, triple output synchronous step-down switching regulator controller with output voltage power up/down tracking capability. The controller allows for sequential, coincident or ratiometric tracking.This 3-phase controller drives its output stages with 120? phase separation at frequencies of up to 700kHz per phase minimizing the RMS input current. Light load efficiency can be maximized by using selectable Burst Mode operation. The 0.6V precision reference supports output voltages from 0.6V to 5V.Fault protection features include output overvoltage, input undervoltage lockout plus current foldback under short-circuit or overload conditions.Applications Servers, Telecom, Industrial Power Supplies General Purpose Multiple Rail DC/DC FPGA and DSP Requirements

The LTC3530 is a wide VIN range, highly efficient, fixed frequency, buck-boost DC/DC converter that operates from input voltages above, below or equal to the output voltage. The topology incorporated in the IC provides a continuous transfer function through all operating modes, making the product ideal for single lithium-ion, two-cell alkaline or NiMH applications where the output voltage is within the battery voltage range.The LTC3530 is pin compatible with the LTC3440 buckboost DC/DC converter but adds programmable automatic Burst Mode operation and extends the VIN/VOUT range to 1.8V. Switching frequencies up to 2MHz are programmed with an external resistor. Automatic Burst Mode operation allows the user to program the load current threshold for Burst Mode operation using a single resistor from the BURST pin to GND.Other features include 1?A shutdown, short circuit protection, programmable soft-start control, current limit and thermal shutdown. The LTC3530 is available in a thermally enhanced 10-lead (3mm ? 3mm) DFN or MSOP package.Applications MP3 Players Handheld Instruments Digital Cameras Smart Phones Portable GPS Units Miniature Hard Disk Drive Power

Demonstration circuit 943 is a complete power controller for a USB power device. It features the LTC6047 and provides a full-featured 1.25A linear lithium-ion CC/CV battery charger with timer termination and 4.2V charge voltage, a USB power manager, and a PowerPath manager for the battery. The USB input voltage range is 4.35V to 5.5V and the wall adapter input is 4.35V to 6V. It also features a programmable 1.5A input current limit that can be set at 500mA or 100mA for USB applications. The wall adapter input has overvoltage protection up to 13V. An external MOSFET disconnects the wall adapter when the voltage exceeds 6V.

Demonstration Circuit 974 is a 100kHz to -500kHz programmable frequency, high voltage, current-mode DC/DC step-down converter featuring the LT3844. The operating frequency can be synchronized up to 600kHz. The board operates from a Vin range of 15V to -60V and outputs 12VOUT @ 4.2A (50W).

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

DC988A-B: Demo Board for the LT3585 Photoflash Charger with Adjustable Input Current and IGBT Driver.

The LT3585 series are highly integrated ICs designed to charge photo?ash capacitors in digital and ?lm cameras. A new control technique allows for the use of extremely small transformers. Each part contains an on-chip high voltage NPN power switch. Output voltage detection is completely contained within the part, eliminating the need for any discrete zener diodes or resistors. The output voltage can be adjusted by simply changing the turns ratio of the transformer.The CHRG/IADJ pin gives full control of the part to the user. Driving CHRG/IADJ low puts the part in low power shutdown. The CHRG/IADJ pin can also be used to reduce the input current of the charger, useful in extending battery life. The DONE pin indicates when the part has completed charging.The LT3585 series of parts are housed in tiny 3mm ? 2mm DFN packages.Applications Digital/Film Camera Flash PDA/Cell Phone Flash Emergency Strobe
