Power Integrations - Compact 25-Watt LED Lighting Ballast Reference Design Sized for T8 Tubes
Power Integrations today published a new reference design for a 25W LED T8 tube ballast power supply. Notable for industry-leading efficiency of greater than 91%, the design (DER-287) also meets commercial requirements for power factor (PF greater than 0.9) and harmonic distortion (EN61000-3-2 Class C). DER-287 is a single-stage converter built around LNK409EG, a member of the LinkSwitch-PH family of LED driver ICs. Single-stage technology greatl...
Power Integrations Introduces Reference Design for 5 W LED Lamps with PFC and Flicker-Free TRIAC Dimming
Power Integrations today announced a new reference design (RDK-251) for a 5-watt offline LED driver that includes flicker-free TRIAC dimming and single-stage power factor correction (PFC). The reference design is based on Power Integrations’ LNK457DG, a member of the innovative LinkSwitch-PL family of LED driver ICs optimized for compact, non-isolated installations.
Integrated power supply control IC Delivers Up to 280% Peak Power
Power Integrations has introduced the TinySwitch-PK integrated power supply control IC with peak power mode. TinySwitch-PK delivers up to 280 percent peak power for short periods of time, enabling designers to specify transformers rated for the continuous power level, significantly reducing size, weight and cost of designs. With its high level of integration and robust feature set, TinySwitch-PK enables simple, flexible designs with far fewer com...
Power Integrations’ New SENZero High-Voltage ICs Eliminate Sense Resistor Power Losses in Standby Mode
Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today introduced SENZero, a family of ICs that disconnect sense resistors from high-voltage rails during standby or remote-off conditions. SENZero devices eliminate sense resistor power losses in standby mode and reduce total system power consumption, helping to meet the stringent demands of energy-conscious equipment makers an...
New power resistors feature high performance levels at lower costs
Recently added to Tyco Electronics’ CGS range of power resistors, new aluminium housed THS series power resistors are based on the high performance HS series devices, featuring same basic performance levels but at lower costs.
Din-Rail Power Supply Holds-Up When Mains Fails
PULS UK has announced its QTD20.241 DIN-Rail power supply for use with AC motors and drives. At only 65mm wide and offering 24VDC at 20A this 95% efficient Din-Rail power supply uses existing system power to provide secure DC for control systems. Modern machines typically use maintenance-free AC-motors that are controlled by frequency converters or servo amplifiers. Such controllers have an intermediate DC-bus to which all individual drives are c...
2 Phase Input Din-Rail DC Power Supply Saves Space
PULS UK has announced the launch of its latest space-saving DIN-Rail mounted power supply. Part of the highly successful MiniLine series the new ML100.200 is designed for phase-to-phase operation at 380-480VAC with no neutral. Taking power between two phases reduces terminal space and costs associated with wiring, fuses and installation time.
