Isolated 12-Port Power over Ethernet PSE Controller Chipset Eliminates Optos for Lowest Solution Cost
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.
DC/DC Regulator Is as Simple as a Linear Regulator But with 98% Less Heat Dissipation and 90% Smaller Design Without Hot Spots
Linear Technology has introduced the LTM8020, the first in a new family of DC/DC uModule regulator systems that operate from higher voltage input supplies of up to 36V (40Vmax). The LTM8020 is a 200mA complete DC/DC solution that includes a DC/DC controller IC, power switches, inductor, compensation circuitry and input and output bypass capacitors. This solution is extremely compact at only 6.25mm x 6.25mm and low profile at 2.3mm in height.
Ultralow Quiescent Current High Power Step-Down DC/DC Controller
Linear Technology has announced the LTC3834/-1, a synchronous step-down DC/DC controller, featuring the industry’s lowest quiescent current. Drawing only 30uA in sleep mode, the LTC3834/-1 is ideal for preserving battery energy in always-on automotive systems or battery-powered devices where the system remains semi-active, or when a car’s engine is off. When in shut down mode, the LTC3834/-1 draws a mere 4uA.
Battery Charger Controllers in Compact 16mm2 Package Require No Blocking Diode
Linear Technology has introduced the LTC4012, LTC4012-1 and LTC4012-2, fast-charge 4A capable high efficiency switchmode battery charger controllers for multiple battery chemistries. The LTC4012 supports Li-Ion/Polymer, NiMH, NiCd and sealed lead acid battery chemistries in single and multicell configurations.
1A VLDO Outputs Down to 0.2V from 0.9V Input
Linear Technology Corporation announces the LT3022, a 1A very low dropout linear regulator (VLDO™), featuring input voltage capability down to 0.9V and adjustable output voltage down to 0.2V. The LT3022's low VIN capability, coupled with the device's low dropout (145mV typical at full load), make it ideal for low-voltage, high current rails in digital ICs such as FPGAs, ASICs, DSPs, microprocessors and microcontrollers. It also has applications...
Programmable Miniature Spread Spectrum Clock ICs
The new programmable subminiature Spread Spectrum Timing (SST) ICs of the PL671 series offered by PETERMANN TECHNIK are revolutionary in price, performance and variability . The customer is able to build up very easily extremely cheap high performance Spread Spectrum Clocks up to 200MHz with high resolution Spread Steps including 4 independent programmable configurations. Take a crystal or a referency input signal together with IC and the low cos...
Spread spectrum quartz oscillator ICs from PETERMANN-TECHNIK
Spread spectrum quartz oscillators in 7 x 5 and 5 x 3.2 mm ceramic cases are becoming increasingly obsolete. The PL671 series programmable spread spectrum oscillator ICs produced by PhaseLink / USA and represented exclusively in Germany by PETERMANN-TECHNIK from Kaufering are much smaller, less expensive and thus far better than the fixed frequency SST quartz oscillators in 7 x 5 and 5 x 3.2 mm ceramic casing.
Clocking Concepts for WiMax
PETERMANN-TECHNIK can supply an extremely wide range of crystals to meet the manifold demands of generating reference frequencies in WiMax applications. These include crystal oscillators (XO, VCXO, TCXO and OCXO) as well as mixed signal oscillator components in the frequency range of 10KHz to 1GHz.
