| Part Number | LM3409 |
| Manufacturer | National Semiconductor |
| Title | PFET Buck Controller |
| Description | The LM3409/09HV are P-channel MosFET (PFET) controllers for step-down (buck) current regulators. They offer wide input voltage range, high-side di... |
| Features |
combine to make the LM3409/09HV ideal for use as constant current sources for driving LEDs where forward currents up to 5A are easily achievable. The LM3409/09HV uses Constant Off-Time (COFT) control to regulate an accurate constant current without t...
