General Description
The G5180 is a single-channel PWM control IC for low
voltage DC/DC conversion incorporating a soft start
function and short circuit detection function. The de-
vice has a low minimum operating voltage of 2.2V and
is ideal for the power supply of battery-operated elec-
tronic equipment.
Applications
„ LCD Displays
„ PDAs
„ Digital Still Cameras
