ON Semiconductor Releases NCL30002 Power Factor Corrected Buck LED Driver

Simplified PFC buck driver application using the NCL30002 The NCL30002 is a switch mode power supply controller intended for low to medium power single stage power factor (PF) corrected LED Drivers. The device operates as a critical conduction mode(CrM) buck controller to regulate LED current at a high power factor for a specific line voltage range. The current limit threshold is tightly trimmed allowing open loop control techniques to reduce parts count while maintaining accurate current regulation and high power factor. CrM operation is particularly suited for LED applications as very high efficiency can be achieved even at low power levels. These are important in LED lighting to comply with regulatory requirements and meet overall system luminous efficacy requirements. In CrM, the switching frequency will vary with line and load. Switching losses are low as recovery losses in the output rectifier are negligible since the current goes to zero prior to reactivating the main MOSFET switch. Read more »

TDK-Lambda Introduces the ZWS-BP 150-240W Single Output Power Supplies for Application with High Start-Up Current and LEDs

TDK-Lambda's new power supplies feature 200% peak power capability to drive high current start up devices TDK Corporation announces the new TDK-Lambda ZWS-BP series of single output, PCB-type AC-DC power supplies. Based on the popular ZWS series, the ZWS-BP is 30% smaller than its predecessor, thus simplifying equipment design and is offered in two mid-power output models – ZWS150BP (150W) and ZWS240BP (240W). With a 200% peak power capability, the ZWS-BP is ideal for use in electromechanical equipment, such as motors, disk drives, pumps, fans and actuators, which require a high initial start-up current. The ZWS-BP is equally well-suited for use in a wide range of light industrial equipment and front-end equipment for broadcast and communications applications, and for applications in indoor and outdoor LED lighting and signage and test & measurement.
