Description
- Application Circuit for L5970D driving up to 6 high current white LEDs. The L5970D is a monolithic step-down power switching regulator, capable to deliver up to 1A of continuous output current. The input voltage range is comprised between 4.4 to 36V. The feedback voltage is 1.23V, but with a resistor divider connected with the internal reference of 3.3V, is possible to reduce the sense resistor voltage. This helps in order to reduce the wasted power and to adjust the LEDs brightness
