R2A20134SP Block Diagram
Description
R2A20134SP is an LED lighting controller IC. The control method is selectable for each system demand, fixed frequency, or zero current detection mode. A high-accuracy LED current feedback system makes LED performance more efficient. Critical Conduction Mode PFC control realizes a high power factor and zero current switching. And, Peak Current Mode makes it possible to reduce external parts and realize a low system cost.

- Application NoteAI-generated Summary: The document presents performance data for the R2A20134 evaluation board under various input voltages. It details operation waveforms, power factor, efficiency, total harmonic distortion (THD), output current, and harmonic current measurements. Load conditions are consistently set at 55 V output voltage and 330 mA output current. The data show how these parameters vary with input voltage ranging from 85 to 265 Vrms, highlighting the board's electrical characteristics and compliance with Class C harmonic limits.
- Application NoteAI-generated Summary: The document presents performance characteristics of the R2A20135 evaluation board under various load conditions. It details waveforms for input voltage, input current, and output current at AC220 V and AC240 V with a load current of 220 mA. Power factor, efficiency, total harmonic distortion (THD), input power, and output current are analyzed against input voltage ranging from 160 to 280 Vrms. The data highlights stable operation and efficiency across the voltage range under specified load conditions.
- Application NoteAI-generated Summary: The document presents performance data of the R2A20134 evaluation board under various input voltages and load conditions. It includes waveforms of input voltage, input current, and output current at AC100 V and AC240 V. Power factor, efficiency, total harmonic distortion (THD), input power, and output current are analyzed against input voltage, all measured with a fixed load of VF=30 V and output current of 267 mA. The data highlights the board's electrical characteristics and efficiency performance.
- Application NoteAI-generated Summary: The built-in oscillator operates at a fixed frequency of 48 kHz with a maximum 50% ON duty, controlled by an external resistor connected to the RT terminal. The error amplifier uses a transconductance amplifier to regulate output based on the feedback pin voltage. The gate driving output can deliver up to 900 mA peak current, optimized for MOSFET zero current switching. Overheat protection activates at 155°C, latching the output until temperature drops below 110°C or VCC falls below 3 V. Overvoltage protection uses a secondary OCP function triggered by CS pin voltage exceeding 2.5 V, stopping gate pulses to prevent damage.
