PoE IC delivers 123 W over 1 Gbps CAT5e cable
Linear Technology Corporation introduces the LTC4279 single-port Power over Ethernet (PoE) controller for power sourcing equipment (PSE), delivering up to 123W of power over CAT-5e cable for power-hungry applications. Demand for higher power delivery comes from a widespread set of applications, including LTE picocell base stations, LED signage, security monitoring systems, home automation and machine […]
Choosing an integration level for power supply functions
Since the first application of the wheel, an element of all practical engineering projects has been the make-or-buy decision. The issue is fractal, arising at every level of the design hierarchy: For any given function, at some level of abstraction, you’ll choose to switch between make and buy. But the decision doesn’t hinge on a […]
Multiphase 60-V synchronous boost controller provides up to 97% efficiency
Linear Technology Corporation announces the LTC3897, a multiphase synchronous boost DC/DC controller with input surge stopper and ideal diode controller. The boost controller drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor requirements, enabling the use of smaller inductors versus the single-phase equivalent. Synchronous rectification increases efficiency, reduces power loss and […]
