International Rectifier has introduced a 600V fully-integrated and protected ballast control IC for advanced linear fluorescent lamp ballasts which incorporate active power factor correction (PFC). The IRS2166D integrates PFC, ballast control and half-bridge driver in a monolithic IC. Its PFC circui...

Fairchild Semiconductor introduces critical conduction mode (CRM) power factor correction (PFC) controller ICs specially designed to meet stringent stand-by power and harmonic regulations affecting ballast, notebook adaptors, LCD TVs and LCD monitors. The FAN7529 and FAN7530 utilize a variable on-ti...

Linear Technology announces the LTC3530, a synchronous buck-boost converter that delivers up to 600mA of output current to a regulated output voltage with inputs above, below or equal to the output. Its input range of 1.8V to 5.5V and output range of 1.8V to 5.25V is compatible with single cell Li-I...

Linear Technology announces the LT3510, a dual current mode PWM step-down DC/DC converter with two internal 2.5A power switches packaged in a 20-lead TSSOP-20E package. Each channel is capable of delivering up to 2A of continuous output current at efficiencies up to 88%. Independent input voltage, f...

Vacuumschmelze presented a family of current sensors for solar inverters. These sensors are used to monitor the AC power output of solar systems into the power grid and measure its DC component. Unlike conventional In a grid-connected system, the direct current produced by the solar modules is conve...
