DESCRIPTION
Output voltage of up to 28V can be derived, and from a 2.5V input three white LED’s can be driven in series. Luminance of the LED’s is controlled by changing the duty cycle of a PWM signal applied to the CE pin. In addition, an internal MOSFET with an Rds-on of 0.3Ω is used. Allow profile and small board area solution can be achieved using a chip coil and an ultra small ceramic output capacitor.FEATURES
