GENERAL DESCRIPTION
The LED current is sensed through an external current sense resistor. The voltage across the sensing resistor is compared with reference level of 0.3V, the error amplified to control the pulse width of the power switch thus to regulate the current flowing the LED. Otherwise, The LP3350 offers external frequency PWM dimming method for a wide range of dimming control. Other features include over current protection (OCP), output over voltage protection (OVP), and under-voltage lockout (UVLO). The LP3350 is available in a space saving SOP-8 (0.5mm pitch) package.
