2A, 1MHz Synchronous Boost Regulator from Linear Technology
Linear Technology has announced the LTC3539/-2, 1MHz/2MHz, current mode, synchronous boost DC/DC converters with output disconnect and integrated soft-start. Their internal 2A switches can deliver output voltages as high as 5.25V from an input voltage range of 0.70V at start-up, (0.5V when running) to 5V, making them ideal for Li-Ion/Polymer or single/multicell alkaline/NiMH applications.
Monolithic Linear USB Battery Charger from Linear Technology
Linear Technology has announced the LTC3558, an efficient, multi-function power management solution for handheld applications. The LTC3558 integrates a stand-alone Li-Ion/Polymer battery charger and two high efficiency synchronous regulators - one buck-boost and one buck - and is offered in a compact low-profile 3mm x 3mm QFN package. The linear battery charger can deliver up to 950mA charge current from a wall adapter supply, or up to 500mA char...
Synchronous 600mA (ISW) Boost & 400mA (IOUT) Buck Regulator with 2.4MHz Switching Frequency in a 3mm x 3mm QFN
Linear Technology has announced the LTC3523/-2, a combination of a 600mA (ISW) synchronous boost and a 400mA (IOUT) synchronous buck regulator in a 3mm x 3mm QFN-16 package. Both the boost and the buck regulators switch at 2.4MHz in the LTC3523-2 (1.2MHz for the LTC3523), and use current mode, synchronous topologies. The LTC3523/-2 operate from an input voltage range of 1.8V to 5.5V, making them appropriate for single cell Li-Ion/Polymer or dual-...

Linear Technology has announced the LTC3100, a triple output converter which includes a 700mA (ISW) synchronous boost regulator, a 250mA (IOUT) synchronous buck regulator and a 100mA (IOUT) LDO in a 3mm x 3mm QFN-16 package. Both the boost and the buck regulators switch at 1.5MHz and use current mode, synchronous topologies.
16A Step Down DC/DC Regulator from Linear Technology
Linear Technology has introduced the LTM4616, a complete dual DC/DC uModule regulator system in a tiny surface mount package. The LTM4616 can regulate either two voltages ranging from 0.6V to 5V at up to 8A each, or one output voltage at up to 16A by sharing current from each output in a multi-phase configuration. The LTM4616’s versatility is extended by its ability to operate from either two different input supply rails ranging from 2.375V to ...
37VIN, 1.2A, 2.5MHz Step-Down DC/DC Converter Withstands 55V Transients
Linear Technology Corporation announces the LT3686, a 1.2A, 37VIN step-down switching regulator. The LT3686 operates within a VIN range of 3.6V to 37V with overvoltage lockout, protecting the regulator and load from transients as high as 55V, making it ideal for load dump and cold-crank conditions commonly found in automotive applications as well as 24V industrial supplies. Its internal 1.85A switch can deliver up to 1.2A of continuous output cur...
Small Footprint 4V-38V Input Voltage Range Synchronous Step-Down DC/DC Controller
Linear Technology has announced the LTC3854, a tiny 2mm x 3mm DFN-12 packaged, wide input voltage range synchronous step-down switching DC/DC controller that drives all N-channel power MOSFET stages. The 4V to 38V input range addresses a wide variety of applications, including most intermediate bus voltages and battery chemistries. The strong on-board MOSFET gate drivers enable high power external MOSFETs to produce output currents up to 20A with...
Surface Mount 500mA LDO Is Easily Paralleled Without Hot Spots
Linear Technology has announced the LT3085, the latest member of a family of next-generation NPN LDOs that can be easily paralleled for heat spreading and are adjustable down to 0 volts with a single resistor. This new architecture regulator uses a current reference rather than a conventional voltage reference to allow sharing between multiple regulators by directly paralleling the pins. Current sharing is set with a small length of PC trace as b...
Isolated Monolithic Flyback Simplifies Design and Eliminates Optocoupler
Linear Technology has announced the LT3573, an isolated monolithic flyback switching regulator with an integrated 1.25A NPN power switch. The LT3573 significantly simplifies the design of a flyback converter since it does not require a third winding or optoisolator and can sense the output voltage directly from the primary side flyback waveform.
36V Input (60V Transient), 1A Fault Tolerant Step-Down Regulator Requires Only 75uA of Quiescent Current
Linear Technology has announced the LT3695, a fault tolerant 1A, 36V input step-down switching regulator. Its Burst Mode® operation keeps quiescent current under 75µA in no load standby conditions.
