A new low power I/Q modulator from Linear Technology enables battery-powered transmitters operating in the 30MHz to 1.3GHz frequency bands, breaking new ground in power consumption, sideband suppression, carrier leakage and dynamic range performance. The LTC5599 modulator, powered from a single 2.7V to 3.6V supply, draws only 28mA current, less than 60% that of alternative solutions-with no performance sacrifice.

Linear Technology Corp. announces the LTC3124, a dual-phase, 3MHz, current-mode, synchronous boost DC/DC converter with output disconnect and inrush current limiting. Dual-phase operation significantly reduces peak inductor and capacitor ripple currents, minimizing component size while delivering lower output ripple versus an equivalent single-phase device.
Linear Technology Corp. introduces the LTM8057and LTM8058, 1.5 W output µModule® (micromodule) DC/DC converters with 2 kVAC galvanic isolation (production tested to 3 kVDC) in a 9 x 11.25 x 4.92 mm ball grid array (BGA) package.
Linear Technology Corp. introduces the LTM2884, a USB µModule® (micromodule) Isolator that combines USB data communications and USB power, and guards against ground-to-ground differentials and large common mode transients.
The LTC3114-1 is a synchronous, current-mode buck-boost converter that delivers up to 1 A of continuous output current from a wide range of power sources, including single-cell Li-Ion, 24 / 28 V industrial rails and 40 V automotive inputs. The LTC3114-1’s 2.2 to 40 V input and 2.7 to 40 V output range provides a regulated output.
Linear Technology announces the LTC3646, a 40 V input capable synchronous buck converter than can deliver up to 1 A of continuous output current from a 3 mm x 4 mm DFN-14 (or thermally enhanced MSOP16) package. It operates from an input voltage range of 4 to 40 V, making it ideal for automotive and industrial applications that require high voltage input capability.
Linear Technology announces the LT3761, a 60 V DC/DC controller designed to operate as a constant-current source and constant-voltage regulator. Its internal PWM dimming generator makes it ideal for driving high current LEDs, but it also has features making it suitable for charging batteries and super-capacitors.
Linear Technology Corp. announces the LTC3375, a highly-integrated general-purpose power management solution for systems requiring multiple low voltage power supplies. The device features eight independent 1A channels with I²C control, flexible sequencing and fault monitoring in a compact QFN package.
Linear Technology Corp. introduces the LTC3864, a high voltage step-down DC/DC controller that draws only 40 µA quiescent current in standby mode with the output enabled in Burst Mode® operation. The 3.5 to 60 V input supply range is designed to protect against high voltage transients, to operate continuously during automotive cold crank and covers a broad range of input sources and battery chemistries.
