Step-down 1.5A Output LED Driver for Lighting
BD9207FPS
| Description |
| The BD9207FPS LED driver with built-in step-down switching regulator incorporates a switching Pch MOSFET. Feedback voltage is as low as 0.2V, mitigating loss across the sense resistor. In addition, 900kHz PWM control enables a smaller coil to be used, reducing mounting area. |
| Features |
- Maximum switching current: 1.5A
- Built-in Pch switching MOSFETs ensure high efficiency operation
- Low feedback voltage (0.2V) results in low loss
- High oscillation frequency: 900KHz (Fixed)
- Integrated phase compensation reduces the number of external parts
- Built-in soft start function
- Equipped with overcurrent protection (OCP) and thermal shutdown (TSD) circuits
- ON/OFF of output possible via STBY terminal
- Compact surface-mount TO252S-5 package
