The emerging trend of smart lighting and Internet of Things requires a new generation of LED drivers. Infineon Technologies introduces the new member of its XDP LED series, the XDPL8221 for cost-effective dual-stage drivers with advanced features. This device combines a quasi-resonant PFC and a quasi-resonant flyback controller with primary side regulation together with a communication interface. A […]
LM5164 100 V, 1 A DC/DC buck converter extends battery life
Texas Instruments introduced a wide-input-voltage (VIN) synchronous DC/DC buck converter with the industry’s best combination of light load efficiency, ease of design and overall power solution cost. The 100-V, 1-A LM5164 step-down voltage converter shrinks board space in rugged battery-powered industrial and automotive power supplies. Used in conjunction with TI’s WEBENCH Power Designer, this new […]
1×1-in railway dc/dc converters tackle demanding environments
The RP12-AR series dc/dc converters are designed for railway rolling stock applications, but they are also suitable for non-railway high-voltage battery applications. Their 5:1 input voltage range of 36-160 Vdc (185 Vdc for 1 sec) allows for all-in-one solutions for 48-V, 72-V, 96-V and 110-Vdc railway systems. They have a built-in class A filter network […]

Switchers say bye-bye to EMI
Electromagnetic interference can emanate from high di/dt loops found in some switch-mode supply topologies. New controllers overcome these difficulties by integrating key components inside the chip package. Tony Armstrong | Power by Linear, Analog Devices Inc. It goes without saying that PCB layout sets functional, electromagnetic interference (EMI) and thermal behavior of every power supply […]
Wide-input-range, dc-dc converters optimized for railway traction
XP Power has introduced two series of wide input range, cost-effective, high-power density dc-dc converters for railway traction and rolling stock applications. The dc-dc converters’ wide input ranges reduce inventory requirements and enable them to be used across a wide range of applications. The 20W rated RDE20 series feature a 4:1 input range covering 24, […]
DC/DC 15/20/30-W 1×1-in converters optimized to drive LDO regulators in low ripple/noise apps
TRACO Power announces the expansion of their THN 15/20/30 WI series of 15, 20 and 30 W dc/dc converters in the standard 1.00 x 1.00 x 0.40” inch package with ultra-wide 4-1 input ranges. These new 15 / 20 / 30 watt 5Vout models with “-A1” suffix feature an extended trim range up to 6VDC. […]
Evaluation platforms wring out dc/dc railway converters up to 240 W
Evaluation platforms for dc/dc railway converters up to 240 W are available in either high voltage (-1) or high current (-2) layouts and include a RIA12 surge stopper. The R-REF04-RIA12-1 and R-REF04-RIA12-2 are complete reference designs for railway applications. The R-REF04-RIA12-1 board is populated with components rated for higher dc input voltages up to 110 […]
Low power dc/dc converters boast precise outputs
RECOM has extended its low power DC/DC portfolio with the R0.5ZX and R1ZX series. The R0.5ZX and R1ZX are based on the 2kVDC isolated low-profile R1SX SMD series but include an internal linear regulator to give a precise, load independent and low noise output. The already low output ripple and noise can be reduced to […]
Motor controllers handle 80-W BLDC without a heat sink
Infineon Technologies AG introduces smart IPM motor controllers featuring full hardware and software integration needed for BLDC motor drives of up to 80W without heatsink. The new iMOTION IMM100 series combines the motor controller IC and a 3-phase inverter stage in a single, highly compact 12 x 12 mm 2 PQFN package. This combination enables BOM count and PCB […]
