New SP6415 provides versatility and space saving with on-board dual drivers
for white LED and OLED sub display backlighting.
MILPITAS, Calif., April 18 /PRNewswire-FirstCall/ -- Sipex Corporation
(Nasdaq: SIPX) today announced the latest addition to its family of white
LED drivers for the portable market, the SP6415. The device features an
inductive boost converter powering two independent drivers for driving the
white LED main panel backlighting and powering the OLED sub-display or
additional white LEDs. The device is offered in a space saving DFN-10
package.
Ideally suited for dual display architectures such as clamshell phones,
the SP6415 can easily be configured to automatically turn off the
sub-display when the phone is open. Each driver output current is
programmed by a single external resistor. PWM dimming is possible via the
enable pin which also is used to put the device into a 1uA showdown which
greatly extends battery life.
With an output voltage up to 20V, as many as 5 LEDs in series can be
powered at over 80% efficiency when the SP6415 is powered from a single
cell lithium Li-Ion battery or internal 3.3V or 5V rails found in most
hand-held equipment. When switching from powering the main display to the
sub-display, voltage is adjusted to maximize efficiency and minimize power
loss. Additionally, the device offers a full protection scheme against
fault conditions such as: over voltage, over current, over temperature, and
under voltage lock up.
Pricing and Availability
The SP6415 is offered in a small lead-free DFN-10 RoHS compliant
package meeting the extended temperature range: -40*deg*C to +85*deg*C. The
device is priced at $1.40 each in quantities of a 1,000 units.
