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
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 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.
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
The Diodes advantage
The AP3154A and AP3156 provide a simple cost effective solution for
small screen LCD backlighting
ƒ Small footprint TSOT23-5
High power density
ƒ Drives multiple 3W LED
Cost sensitive solution to MR16 lamps
ƒ PWM and DC dimming
Versatile dimming; DC for thermal control, PWM for brightness control
ƒ High switching frequency up to 700kHz
Small inductance value and size
ƒ Green mold compound (No Br, Sb) and Pb-free RoHS compliant
finish
Better for environment; no mercury unlike CFL.
