品牌:GMT(致新)
封装:TQFN3.5X3.5-20
批号:22+
数量*:15000
描述:General Description
The G2548/A/B/C is a high efficiency driver for
whites LEDs. It is suitable for single/two cell battery
input to drive LED light bars which contains six
strings in parallel and up to 12 WLEDs per string.
The internal current sinks support a maximum of
2% current mismatching for excellent brightness
uniformity in each string of LEDs. To provide
enough headroom for current sink operation, the
boost controller monitors the minimum voltage of
the feedback pins and regulates an optimized
output voltage for power efficiency.
The G2548/A/B/C has a wide input voltage operating
range from 4.2V to 24V and contains I2C interface for
controlling the dimming mode, operating frequency
and the LED current. The internal 250m, 37V power
switch with current control provides over current
protection. The switching frequency of the
G2548/A/B/C is also adjustable from 100kHz to
1.6MHz, which allows flexibility between efficiency
and component size.
The G2548/A/B/C are available in the
TQFN3.5X3.5-20 or TQFN3X3-24 package.
