General Description
The XL3002 is a 260 KHz fixed frequency
PWM buck (step-down) DC/DC converter,
capable of driving a 1.5A load with high
efficiency, low ripple and excellent line and
load regulation. Requiring a minimum
number of external components, the regulator
is simple to use and include internal
frequency compensation and a
fixed-frequency oscillator.
The PWM control circuit is able to adjust the
duty ratio linearly from 0 to 100%. An enable
function, an over current protection function
is built inside. An internal compensation
block is built in to minimize external
component count.
Applications
n MR16 LED Lamp
n LED Lighting

Note1: Stresses greater than those listed under Maximum Ratings may cause permanent damage
to the device. This is a stress rating only and functional operation of the device at these or any
other conditions above those indicated in the operation is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
