92% Efficient 100mA Synchronous Buck Converter From Linear
Linear introduce a 150V input-capable synchronous buck converter that delivers up to 100mA of continuous output current. The LTC3639 operates from an input voltage range of 4.5V to 150V, eliminating the need for an external transient suspension device. The LTC3639 utilizes internal synchronous rectification and a programmable peak current-mode design to optimize efficiency over a broad range of output currents.
PCIM Europe: Power MOSFETs Provide High Blocking Voltage
Advanced Power Electronics announced three new high voltage MOSFETs – AP11S60-HF-3, AP14S50-HF-3 and AP20S60-HF-3 – that offer improved on-resistance and gate charge to provide low conduction and switching losses, making switching applications more efficient. The devices are the first in a series of competitively-priced parts that will be introduced by the company and feature RDS(ON) as low as 0.19Ω (AP20S60-HF-3)
