A8169-025 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.

A8169-025 Key Features
- current step-up DC/DC converter ideal for driving LEDs
- used in backlighting
A8169-025 Applications
- 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(ON) of 0.8Ω is used. Allow
