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 […]
Miniature HV SMT Gas Discharge Tube Withstands 3 kA@8/20 μsec
Littelfuse today introduced its first high voltage, surface-mount gas discharge tube (GDT) with two squared terminals that is capable of withstanding surge currents of 3kA@8/20μs in a small form factor. CG4 Series Two-Terminal High Voltage Miniature Gas Discharge Tubes are high voltage (800V – 3000V) devices designed for over-voltage protection for high isolation applications. They […]
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 […]
Small LDOs target automotive safety modules
ROHM has recently announced the availability of the world’s smallest LDO regulators designed for automotive safety modules requiring greater reliability and increased miniaturization, such as sensors, cameras, and radars in ADAS (Advanced Driver Assistance System) applications. In recent years, the proliferation of accident prevention measures and automated driving systems are demanding advanced safety systems that […]
DC-DC converters with renewable energy in mind
Modern battery, fuel cell and solar cell systems need ways of transferring power in two directions. New dc-dc converters that are bidirectional can eliminate the need for bulky transformers in these applications while bringing more efficient operation. ANKUR PATEL VICOR CORP. ALTERNATIVE energy scenarios involving renewable sources are characterized by the sending of power both […]
SMD DC-DC converters offer 1.5 kV isolation
XP Power today announced three high-performance ranges of surface mount (SMD) DC-DC converters rated at 1, 3 and 6 Watts of output power with single and dual outputs. The ISB series provides 1W of output power, the ISC 3W and the ISX is a 6W converter. The small size of the converters takes up less […]
40-V, 2.1-A Rail-to-Rail LDO now works at 150°C
Linear Technology Corporation announces a new higher temperature “H-grade” version of the LT3086 in the TSSOP package. The LT3086 is part of Linear’s feature-rich LDO+™ family, offering significant functionality previously unavailable in linear regulators. The 40V, 2.1A low dropout linear regulator (LDO) includes current monitoring with externally settable current limit and temperature monitoring with external […]
ICs provide sinusoidal drive for 3-phase BLDC motors
ON Semiconductor has announced three new devices for driving 3- phase BLDC motors via 180 degree sinusoidal waveforms. Designed for use in cooling fans of household appliances such as refrigerators, as well as games consoles and computing equipment, the LV8811, LV8813, and LV8814 have voltage ranges of 3.6 volts (V) to 16 V, 6 to […]
Why power modules can work better
than discrete power circuits
The example of an ISL8203M power module shows how designers typically size up the decision between devising a power circuit using discrete components versus spec’ing–in a ready-to-go module. Jian Yin, Intersil Corp. Power modules are the way to go when it comes to getting your design to market quickly, but choose wisely. Power-module architecture choices […]
