Comm Equip Makers Demand High Power Output & Small Footprint

Figure1. LTM4622(A) Can Be Mounted on the Underside of a PCB

Many communications systems are powered via a 48V backplane. This voltage is normally stepped down to a lower intermediate bus voltage, typically to either 12V, 5V or even lower, in order to power the racks of boards within the system. However, most of the sub-circuits or ICs on these boards are required to

Inverter Efficiency

Click image to enlarge

At least two power reactors are needed for solar inverters: one in the boost converter (step-up chopper) and one at the ouput of the inverter for EMC filtering. Besides the IGBTs, the losses in the reactors are a major determining factor of the overall efficiency of the inverter

Low-loss and high saturation flux density core materials in reactors and transformers are a key determining factor for the efficiency of inverters. The new TDK PE90 ferrite is a cutting-edge

Figure 1: Example PLD, with 12 inputs, 8 product terms and 4 macrocells
PLDs can have hundreds of macrocells with up to 16 product terms driving each macrocell. The AND and OR gates within the product terms can be interconnected to form highly flexible custom logic functions. The macrocells are typically clocked, and their outputs can be fed back into the product term array. This allows state machines to be created.

In most microcontroller architectures, there is a smart' CPU surrounded by a set of relatively dumb' peripherals. Peripherals have limited functions; converting data from one form to
