Off-line Converters for Compact Power Supplies with High Efficiency in All Load Ranges [STR3W400MXD Series]

Feb. 09, 2024

Product Category: ICs >Power Management ICs > Off-line Converters

The STR3W400MXD series are off-line converter ICs with green mode that optimizes oscillation frequency according to load. The green mode decreases an oscillation frequency to a load-appropriate level and thus reduces switching losses in a power MOSFET. This allows you to build a power supply that yields high efficiency in all load ranges.
These ICs will best suit applications where efficiency at light to medium loads needs to be regulated, such as by the ErP Directive.
The STR3W400MXD series comes in a TO220F-6L package, making your power supply more compact and cost-effective.

    Features
    Higher Efficiency in All Load Ranges

Low-noise, High-voltage, 3-phase Motor Driver with Temperature Sensing Function [SIM6895M]

Sep. 28, 2023

Product Category: ICs > Motor Drivers > High Voltage 3-phase Brushless DC Motor Drivers

Our new product, the SIM6895M, a high voltage 3-phase motor driver for large home appliances, has been put into mass production.

Sinusoidal, High-voltage, 3-phase Brushless DC Motor Driver for 10-pole DC Motors [SX68128MB]

Mar. 09, 2023

Product Category: ICs >Motor Drivers > High Voltage 3-phase Brushless DC Motor Drivers


The SX68128MB is a high voltage 3-phase motor driver, which is driven by a sinusoidal control and suitable for 10-pole DC motor systems.
In general, a 10-pole DC motor needs a 15-pulse rotation signal to rotate, whereas a conventional 8-pole DC motor needs a 12-pulse rotation signal. For this reason, it is necessary to design another dedicated system if your application uses a 10-pole motor.
The SX68128MB, on the other hand, is capable of outputting a 12-pulse rotation signal even for a 10-pole DC motor. This means you can incorporate a 10-pole motor without changing your existing 8-pole DC motor system.

The product is offered in a thin SOP36 package, where a controller, a gate driver, the output transistors of three phases, and bootstrap diodes are highly integrated. And you can configure a motor drive circuit with fewer external components. Its compactness consequently helps you build a motor drive circuit that is highly reliable but low capacity.
The product also supports Hall elements and Hall IC inputs.

The SX68128MB will be best suited for inverter control systems using low- to medium-capacity motors compliant with universal input standards, such as fan motors for air conditioners, air purifiers, and electric fans.

Product Category: ICs >Motor Drivers > High Voltage 3-phase Brushless DC Motor Drivers


The SIM2-151A is a high voltage 3-phase motor driver in which transistors, pre-drive circuits, and bootstrap circuits (diodes and resistors) are highly integrated.
The new product comes in a compact DIP40 package and will best suit compressor-driven applications such as refrigerators and air conditioners.

Along with the lower-loss power elements, we successfully reduced the product’s mold volume by 40% or more compared to our conventional package through the DBC (Direct Bonding Copper) structure—whose excellent heat dissipation is a promising feature. The SIM2-151A also achieves the industry’s smallest size* among the high-voltage motor driver ICs rated for 15 A.
The product is available in the package with not only a decreased volume size but also the heat dissipation equivalent of the conventional package.

Harmonics Standard Compliant: 1-converter System, High-power-factor LED Drivers [LC5581AS, LC5581LS]

Dec. 19, 2022

Product Category: ICs > Power Management ICs > LED Drivers

We are announcing that our new LED driver ICs, LC5581AS and LC5581LS, are now in mass production.
The products employ the 1-converter system requiring no input electrolytic capacitor and comply with the harmonics standard (IEC 61000-3-2 Class C) even in operations at light load.
The following features will benefit your application: the average current control to yield high power factors; the quasi-resonant operation that helps you design a high-efficient and low-noise power supply; the PWM mode as a user-selectable operation mode.
With the built-in startup circuit having a high breakdown voltage of 800 V, your application will be able to use power MOSFETs up to 800 V. And this allows you to come up with a power supply which is durable and safely operable even in a region with unstable input voltages.
The products also incorporate the standby function and the analog dimming function that controls the brightness of a light source with externally applied voltages. Their configurable circuit topologies include isolated/non-isolated flyback circuits and non-isolated converter circuits, thus offering you application-based choices.
Two different types of overvoltage protection (OVP) are available in our product lineup: the LC5581AS of the auto-restart type, and the LC5581LS of the latch type.

Small-sized, High-current Schottky Diodes with Trench Structure [FMES Series]

Oct. 21, 2022

Product Category: Discretes > Diodes > Schottky Diodes

We have recently started mass production of new high-current Schottky diodes — FMES series.

Not only the downsized packaging, this series also brings a significant reduction in the leakage current at high temperature, H・IR. Having a higher critical point of thermal runaway temperature than that of a competitor’s similar product*, the FMES series allows a thermal design with sufficient margins.

* Based on the findings from our own FMES-24010 evaluation.

Product Category: LEDs > Visible Light LEDs > Surface Mount Flat Type LEDs

The SEP1A series are high color rendering LED devices that have quality defined by not only the average color rendering index, Ra, but also the special color rendering index, Ri. By using our LEDs, you can realize lighting fixtures with the same performance as color rendering AAA fluorescent lamps for color evaluation. The SEP1A series, developed with our own color rendering improvement technology, can maintain the industry's highest luminous efficiency while achieving high color rendering. This leads to the energy-saving effect* over 2 times higher than color rendering AAA fluorescent lamps. Based on these advantages, the SEP1A series can also be used as a light source for lighting equipment which require high color rendering, such as task lighting and museums lighting. In addition, our LED devices suppress ultraviolet components and thus promise preventive effects against discoloration of exhibits.
* Energy-saving performance depends on the design of lighting equipment.

  
Characteristics* and Features   
  • Average color rendering index: Ra ≥ 95
  • Special color rendering index: Ri ≥ 90 (i = 9 to 15)
