| Description | High Current and Performance White LED Driver |
|
|
The HT7939A is a high efficiency boost converter for driving multiple White LEDs using current mode operation. The device is designed to drive up to 39 White LEDs from a 5V power supply. The White LED current is setup using an external current setting resistor, which has a low feedback voltage of 0.2V to minimise resistor power losses and thus improving efficiency.
