G5162
G5162
Off-Line Digital Green-Mode LED Driver, Charger
Integrated with Power BJT
1.0 General Description
The G5162 is a high performance AC/DC
power supply control device which uses
digital control technology to build peak
current mode PWM flyback power supplies.
This device includes an internal power BJT
and operates in quasi-resonant mode to
provide high efficiency along with a number
of key built-in protection features while
minimizing the external component count,
simplifying EMI design, and lowering the
total bill of material cost. The G5162
removes the need for secondary feedback
circuit while achieving excellent line and load
regulation. It also eliminates the need for
loop compensation components while
maintaining stability in all operating
conditions. The built-in power limit function
enables optimized transformer design in
universal off-line applications and allows for
a wide input voltage range.
GlobalSemi’s innovative proprietary
technology ensures that power supplies built
with the G5162 can achieve the highest
average efficiency, lowest standby power
consumption, and fast smooth startup with a
wide range of output voltage, that are ideal
for LED lighting applications.
