Design kit eases control of power factor
International Rectifier has introduced the IRAC1150-D2 power factor correction (PFC) control design kit and added a PFC design tool to the myPower online design centre.
International Rectifier has introduced the IRAC1150-D2 power factor correction (PFC) control design kit and added a PFC design tool to the myPower online design centre The design features the IR1150 uPFC for AC/DC PFC and is a small, 710mm-square fully assembled PFC control circuit that engineers can drop in to an existing power supply, replacing its old continuous conduction mode (CCM) PFC circuit

MOSFETs improve 12V-input converter efficiency
Two new 20V HEXFET power MOSFET families from International Rectifier are designed to increase efficiency by up to 4% in 12V-input DC/DC convertors.
Designing with the IR1150 is simplified with the aid of a two-step process online design tool: users simply enter system requirements, and the design tool generates a complete bill of materials.
The design tool simplifies active PFC development so that designers can replace old, passive solutions with poor power factors and low efficiency with modern, more efficient solutions.
The reference design kit comes complete with an assembled and tested reference design board, five IR1150STR ICs, two 8ETX06 Hyperfast rectifiers, user's guide, application notes, device datasheets and printed circuit board files (Gerber, DXF and CAD).
The IR1150 PFC control IC, offered in a compact SO-8-package with a lead-free option, cuts PFC control board space as much as one-half, and enables a simplified and flexible high density solution for computing, consumer electronics and home appliances from 75W to 4kW.
Featuring IR's one cycle control (OCC) approach, the device delivers the performance of continuous conduction mode (CCM) PFC with the simplicity, reliability and low component count of a discontinuous current mode (DCM) circuit for PFC applications.
With unity PF as the ultimate goal, the IR1150 enables 0.999 PF with only 4% total harmonic distortion, enabling AC/DC applications to conform to international legislative requirements such as IEC1000-3-2 in Europe, JIC C61000-3-2 in Japan and the China Compulsory Certificate (CCC) for products using more than 75W.
As manufacturers implement PFC in response to these energy standards, the IR1150 control IC simplifies effective PFC solutions, and enables a single design that can be used worldwide.
The IRAC1150-D2 reference design board is available immediately.
Pricing is US $195 each and is subject to change.
The online PFC design tool is available at no charge, after registering on the myPower design centre.
