R2A20134 is a new LED Driver IC, in the electronic components it acts an important role and have its own features that attracts people. The following is its 3 features why people like it.
1. R2A20134 reduced system cost
R2A20134 was launched by Renesas Electronics company, its exclusive voltage step-down control technology (single-stage) provides a high line-to-ground voltage. In addition, the ability to select low-voltage MOSFETs (voltage tolerance of only 500 volts (V) to 300 V, rather than the typical 700 V) further contributes to lower system cost.
2. R2A20134 has high efficiency and a high power factor
The use of Renesas Electronics' exclusive high-voltage control and critical-conduction mode (Note 1) enable zero-current switching at turn-on and switching in a low drain-source voltage state. As a result, the new LED driver IC enables reduction of power loss during switching and achieves the industry-leading power factor (Note 2) of 92 percent (Note 3) by reducing the power loss during switching. In addition, critical-conduction mode allows PFC (power factor correction) control using few external components and realizes a power factor of 0.9 or higher.
3. R2A20134 supports for various LED control modes
A variety of control modes can be achieved by changing the configuration of the externally connected elements. Examples include buck-boost control, average-current control, peak-current control, and constant-input-power control.
The R2A20134 LED driver IC also can be employed in TRIAC dimmer applications by applying a voltage matched to the TRIAC phase to the FB (feedback)pin for constant-current control. The company additionally supplies drive MOSFETs meeting a variety of power and performance requirements.
With these 3 features of R2A20134, can't it hot in electronic components industry?
