| Manufacturer | National Semiconductor |
| Description | The LM3434 is an adaptive constant on-time DC/DC buck (step-down) constant current controller (a true current source). The LM3434 provides a constant current for illuminating high power LEDs. The outp... |
| Features |
include thermal shutdown, VCC under-voltage lockout, and logic level shutdown mode. The LM3434 is available in a low profile LLP-24 package.
Features
■ Operating input voltage range of -9V to -30V w.r.t. LED anode ■ Control inputs are referenced to the LED anode ■ Output current greater than 6A ■ Greater than 30kHz PWM frequency capable ■ Negative output voltage capability allows LED anode to be tied directly to chassis for maximum heat sink efficacy ■ No output capacitor required ■ Up to 1MHz switching frequency ■ Low IQ, 1mA typical ■ Soft start ■ Adaptive programmable ON time allows for co... |
