Built-in Flash Timeout Protects High-Power LEDs From Thermal Runaway
MILPITAS, Calif., July 11 /PRNewswire-FirstCall/ -- Sipex Corporation
(OTC: SIPX.PK), today announced its newest Flash LED driver IC, the SP7685.
With 1.2A output current, the SP7685 is an ideal solution for driving the
next generation of high intensity white LEDs. The device features
programmable Flash current and Torch mode where constant light is needed.
Operating at an industry leading 2.4MHz switching frequency, the SP7685
requires only five small external components thus reducing the overall
solution footprint to new levels. Another significant feature of the SP7685
is the two second timeout function at Flash mode. This built-in protection
feature enables reliable high-power LED operation over a long life cycle.
SP7685 is designed to fulfill high-power LED needs for a variety of
applications, including 2+ megapixel camera phone, Xenon-LED dual lighting
video camcorder, and 5W LED flashlights.
The SP7685 provides designers with many other features critical to
handheld battery operated systems:
-- Automatic soft start: limits inrush current
-- High efficiency: up to 94% in Torch Mode
-- Minimum external components
-- Wide VIN range: 2.7V to 5.5V
-- Low 50mV reference for low loss sensing
-- IQ < 1uA in shutdown
-- Over-voltage protection on output
-- Over-current/temperature protection
-- Low ripple and EMI - no inductors
-- Space Saving 10-pin 3mm x 3mm DFN Package
"Sipex is committed to providing product solutions and features that
support the latest LED technology while addressing system requirements,"
said Chris Lee, Technical Marketing Manager. "The SP7685 is pin-to-pin
compatible with Sipex's successful SP6685 700mA LED flash driver. The
SP7685 integrates flash mode timeout, thermal runaway, over-current, and
over-voltage features to ensure the high power driving condition is safely
protected."
Pricing and Availability
The SP7685 is available in industry standard 3x3 DFN-10 packaging, in
an extended temperature range from -40 degrees C to +85 degrees C. Pricing
is $1.50 in 1K units. Datasheets and additional support documentation can
