Regulators
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 […]
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 […]
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 […]
Regulator combines SEPIC, inverting conversion for dual outputs
Linear Technology introduces the LTM8049, a dual output, two-function DC/DC µModule® (power module) regulator in 15mm x 9mm x 2.42mm BGA package. One function is SEPIC (single-ended primary-inductor converter) in which the output voltage is regulated while the input voltage can vary to be less, equal or more than the value of the output voltage. […]
ZVS Buck-Boost Regulators handle 200 W with 97% efficiency
Vicor Corporation announced the addition of two new buck-boost regulators to its Cool-Power® ZVS Regulator portfolio. Delivering up to 200 Watts at greater than 97% efficiency, these new Cool-Power Regulators incorporate Vicor’s proprietary high-frequency zero-voltage switching (ZVS) technology and feature best-in-class conversion efficiency, power density, and performance. Engineered and optimized as a complete solution, PI3741-0x […]
Power regulators handle high-power, low-voltage sub-28-nm GPUs, FPGAs, ASICs, and processors
Linear Technology Corp. introduces the LTM4650-1A and LTM4650-1B, dual 25A or single 50A µModule (power module) regulators scalable to deliver 300A to high power, low voltage sub-28nm GPUs, FPGAs, ASICs and microprocessors. The low core voltage of these digital devices requires very accurate voltage regulation at both steady state (DC) and fast load current transients. The […]
High-Efficiency, High-Current Buck-Boost Regulators target battery-powered portable apps
Intersil today announced the ISL91127 and ISL91128 high-efficiency buck-boost regulators. The latest in Intersil’s industry-leading buck-boost family, the new devices feature 4.5A switches, best-in-class efficiency up to 96%, and a compact footprint ideal for providing system power or powering the peripherals in battery-operated devices. They offer the industry’s lowest quiescent current of 30µA for superior […]
Synchronous Rail-to-Rail Step-Down Regulator Sinks/Sources ±5 A
Linear Tech Corporation announces the LTC3623, a ±5A high efficiency, current mode synchronous buck regulator that is adjustable from 14.5V down to 0V output with a single resistor. Proven on Linear Technology’s prior linear regulators and switching regulators, this innovative architecture uses a 50µA current reference, combined with a single resistor, to set the output […]
