| Part Number | IS31LT3505 |
| Manufacturer | ISSI |
| Description | The IS31LT3505 is a constant current step-up converter with internal NMOS. The step-up converter topology allows series connection of the white LEDs so the LED currents are identical for uniform brightness as well as constant output voltage to drive other devices. The output current of each channel can be set by an external resistor and dimming the brightnes. |
