DESCRIPTION
FEATURES
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 CE pin.
In addition, an internal MOSFET with an RDS(...
