Devices Reduce Component Overhead
DALLAS--(BUSINESS WIRE)--Mar. 24, 2009--
Diodes Incorporated (Nasdaq:DIOD), a leading global manufacturer and
supplier of high-quality application specific standard products within
the broad discrete and analog semiconductor markets, introduced a family
of LED driver ICs capable of significantly reducing the number and size
of external components required by driver circuits. The AP880X step-down
DC-DC converters require the support of only four components and operate
at switching frequencies up to 600kHz, which enables the use of smaller,
lower cost inductors and capacitors.
Designed to drive series-connected LEDs with a constant current, the
AP880X family supports up to 13 LEDs from voltage sources between 8V and
48V. The drivers are suitable for a broad range of high-brightness,
general illumination applications, including signage, architectural,
emergency lighting and MR16 lamp replacement, ensuring uniform LED
brightness as well as eliminate the need for ballast resistors.
For an operating voltage range from 8V to 28V, the AP8800 furnishes a
string of seven LEDs with a current up to 350mA, providing a cost
effective match for 1W LED systems. For higher output power, the AP8801
produces a drive current of 500mA from an operating voltage of 8V to 48V
to support up to 13 series-connected LEDs.
The third product in the driver family, the AP8802, meets the
requirements of high power 3W LED systems. For an operating voltage
range from 8V to 48V, the AP8802 driver provides up to 13 LEDs with a
constant LED current of up to 1A. All three devices deliver efficiencies
up to 92 percent.
To reduce the stress on LEDs, the AP880X drivers feature an integrated
soft-start function, which helps to extend LED lifetime. The drivers
also offer the choice of PWM and DC input dimming control in order to
increase design flexibility. All devices are packaged in the industry
standard SOP-8L package. The AP8800 and AP8801 are also available in
MSOP-8L and the AP8802 in exposed pad DFN and SOP-8L packages.
