Ultralow-noise LDO delivers up to 50 0mA output with a 260-mV dropout
Linear Technology announces the LT3045, an ultralow noise, ultrahigh power supply ripple rejection (PSRR) low dropout voltage linear regulator, a higher output current version of the widely accepted 200mA LT3042 ultralow noise LDO. The LT3045’s unique design features ultralow spot noise of only 2nV/√Hz at 10kHz and 0.8μVRMS integrated output noise across a wide 10Hz […]
2.5A, 42V synchronous step-down switching regulator delivers 95 percent efficiency
Linear Technology Corporation announces the LTC3126, a 2.5A, 42V synchronous step-down switching regulator with an integrated dual input PowerPath™ control. A unique power stage topology enables operation from either of two independent power sources, with seamless, internally controlled transitions between inputs to ensure a stable output voltage during hot-plug and power source disconnect events. Internal […]
RMS power detector operates up to 30 GHz
Linear Technology introduces the LTC5596, a high-frequency, wideband and high dynamic range RMS power detector that provides accurate, true power measurement of RF and microwave signals independent of modulation and waveforms. The LTC5596 responds in an easy to use log-linear 29mV/dB scale to signal levels from–37dBm to –2dBm, at accuracy better than ±1dB error over […]
Converter for 48/12-V vehicle dual-battery systems handles more current
Linear Technology Corporation announces the LTC3871, a 100V/30V bidirectional two-phase synchronous buck or boost controller, ideal for 48V/12V automotive dual battery systems. Current 12V automotive systems are reaching their 3kW power limit due to the ever-increasing demand for more electrical devices. A newly proposed standard, LV148, combines a secondary 48V bus with the existing 12V […]
CAN transceiver/isolator guards against big transients
Linear Technology Corporation introduces the LTM2889, a fully ISO 11898-2 compliant CAN (controller area network) µModule (micromodule) transceiver and isolator that guards against large ground-to-ground differentials and common mode transients in 3.3V or 5V applications. In practical CAN systems, ground potentials vary widely from node to node, often exceeding the tolerable range, which can result in […]
IEEE 802.3bt powered device interface controller lets apps get 71 W
Linear Technology Corporation introduces the LT4295 IEEE 802.3bt powered device (PD) interface controller for applications requiring up to 71W of delivered power. The next Power over Ethernet (PoE) standard – IEEE 802.3bt – enables manufacturers to go beyond the 25.5W allocated by the 2009 IEEE 802.3at standard. Linear Technology is poised to be first to […]
Power and energy monitor checks 0 to 15-V dc supply rails
Linear Technology Corporation introduces the LTC2947 power and energy monitor for 0V to 15V DC supply rails. Most power and energy monitoring ICs use an external sense resistor to measure current. However, choosing a sense resistor is not an easy task, especially when dealing with high currents, where available sense resistors can dissipate too much […]
Prioritizer switches 18-V systems over to batteries in the event of power loss
Linear Technology Corporation introduces the LTC4420, a dual input monolithic power prioritizer for 1.8V to 18V systems. To enable portability, preserve memory during brownouts, and ensure a graceful shutdown on power loss, electronic systems employ batteries and capacitors for backup power. The LTC4420 normally powers the load from the higher priority main supply such as […]
60-V Synchronous Buck Charger handles 20-A Lead-Acid, Li-Ion Charge Currents
Linear Technology Corporation introduces the LTC4013, a highly integrated, high voltage multi-chemistry synchronous step-down battery charger controller. With a wide input voltage range that spans up to 60V, the LTC4013 uses temperature-compensated 3- and 4-stage charge algorithms to efficiently charge 12V and 24V lead-acid batteries. Alternatively, the LTC4013 will charge a multicell Lithium-based battery stack […]
