DESCRIPTION
The A8169-025 Series is a fixed frequency, constant current step-up DC/DC converter ideal for driving LEDs used in backlighting applications on cellular phones, PDAs and digital cameras etc. Output voltage of up to 23V can be derived, and from a 3.2V input six white LED’s can be driven in series or alternatively, using a 2.5V input, a network of two parallel legs with three in each may be driven.
Luminance of the LED’s is controlled by changing the duty cycle of a PWM signal applied to the EN pin. In addition, an internal MOSFET with an RDS(ON) of 0.8Ω is used. Allow profile and small board area solution can be achieved using a chip coil and an ultra small ceramic output capacitor (CL) of 0.22uF.
The A8169-025 is available in SOT-26 package.
