Linear Technology has introduced the LTC3836, a dual output 2-phase, low input voltage current mode synchronous step-down switching controller. Operation from an input voltage from 2.75V to 4.5V makes the device ideal for 3.3V, single cell Li-Ion, multi-cell Alkaline or NiMH input sources. It can generate two independent output voltages as low as 0.6V, powering the latest generation of low voltage DSPs and microcontrollers.

Linear Technology has introduced the LTC4263, an autonomous single-channel Power Sourcing Equipment (PSE) controller with an onboard MOSFET for use in IEEE 802.3af Power Over Ethernet (PoE) compliant systems. Requiring only a few external components, the IC is a complete single-port PSE solution that detects, classifies and provides isolated 48V power to Powered Devices (PDs) connected to it. Offering standard-compliant AC or DC methods to sense ...

Linear Technology has introduced the LTC2952, a versatile power management IC with push-button on/off control for system power and system monitoring features. The power management function features two ideal PowerPath controllers suitable for applications requiring an ideal diode-OR function for load sharing or automatic switchover between two input power sources. The low loss switchover is achieved by regulating two external P-channel MOSFETs wi...

Linear Technology Corporation introduced the LTC4449, a high speed synchronous MOSFET driver designed to drive upper and lower power N-channel MOSFETs in a synchronous rectified converter topology. This driver, combined with one of Linear Technology's DC/DC controllers and power FETs forms a complete high efficiency synchronous regulator that can be used as a step-down or step-up DC/DC converter.

Linear Technology has introduced the LTC4269-1, LTC4269-2 and LTC4278, IEEE 802.3at compliant Power over Ethernet (PoE+) interface controllers with integrated switching regulators for high-power Powered Device (PD) applications up to 25.5W and beyond. The new IEEE 802.3at definition, also known as the PoE+ standard, simultaneously expands the power budget and improves the classification mechanism used by Power Sourcing Equipment (PSE) and PDs to ...

Linear Technology has announced the high reliability (MP-grade) version of the LT1952/-1, LTC3900 and LT4430. These devices combine to create a high efficiency (up to 95%) synchronous rectified isolated forward converter that is specified and production tested over a -55°C to 125°C operating junction temperature range.

Linear Technology Corporation annonce les versions de classes H et MP du LTC3851A, un contrôleur DC/DC, abaisseur, synchrone, à large gamme de tensions d’entrée (4V à 38V), convenant à une large gamme d’applications, comprenant la plupart des tensions intermédiaires de bus et de batteries chimiques. Les robustes pilotes de grille de MOSFET, embarqués, permettent l'emploi de MOSFET externes, de forte puissance, pour fournir des intensi...

Linear Technology introduced the LTC4270/ LTC4271 isolated 12-port Power Source Equipment (PSE) controller chipset designed for use in IEEE 802.3at (PoE+) Type 1 and Type 2 compliant Power over Ethernet (PoE) systems.

Linear Technology Corporation introduces the LTC4266A and LTC4274A, 4-port and single-port Power over Ethernet (PoE) controllers for Power Sourcing Equipment (PSE), delivering up to 90W of power to Powered Devices (PDs). The current IEEE standard, 802.3at (also known as PoE+), limits the maximum available power to PDs to 25.5W. By the time the standard was ratified in 2009, applications were already demanding higher power levels. The LTC4266A and...

Linear Technology has introduced the LTC3785, a 96% efficient buck-boost switching regulator controller that operates from input voltages above, below or equal to the output voltage for powering tablet PCs, handheld instruments, wireless modems, portable media players and a wide variety of single or dual-cell Li-Ion or multi-cell alkaline/NiMH powered devices.
