AP8803

Cost effective 3W LED driver for

consumer applications

Description

The AP8803 is a step‐down DC/DC 

converter designed to drive LEDs 

with a constant current. 

The device can drive up to 7 LEDs, 

depending on the forward voltage 

f h LED i

i

f

of the LEDs, in series from a 

voltage source of 8V to 30V. Series

connection of the LEDs provides 

identical LED currents resulting in 

uniform brightness and 

eliminating the need for ballast 

resistors. 

The Diodes advantage

The AP3154A and AP3156 provide a simple cost effective solution for

small screen LCD backlighting

Small footprint TSOT23-5

High power density

The AP8803 switches at frequency 

up to 700kHz. This allows the use 

of small size external components. 

The TSOT23‐5 package and 

coupled with it requiring only 4 

external components produces a 

small solution footprint.

High power density

Drives multiple 3W LED

Cost sensitive solution to MR16 lamps

PWM and DC dimming

Versatile dimming; DC for thermal control, PWM for brightness control

High switching frequency up to 700kHz

Small inductance value and size

The accuracy, temperature range 

and cost make it ideally suited to 

cost sensitive domestic lighting 

application.

It is available in green mold 

compound as standard
