DESCRIPTION
The JW
®
1130H is a current mode monolithic LED
driver. The LED current can be controlled with an
analog input voltage.
With high-side LED current sensing, the
JW1130H can be configured as buck, boost or
buck-boost topology to serve different LED driver
need.
The integrated 44V/2A N-Channel MOSFETs
ensures high efficiency operation.
At light loads, JW1130H operates in low
frequency to maintain high efficiency and low
output ripple.
The overvoltage lockout protection on SW pin
protects JW1130H from open LED fault.
JW1130H also has thermal protection at 140ºC.
The JW1130H is available in a 6-pin SOT23-6and
a 8-pin ESOP8 package, which provides a
compact solution with minimal external
components.
