产品概述 返回TOPS1g嘉泰姆
The CXLE8849 is a 150KHz fixed frequency
PWM buck (step-down) DC/DC converter,
capable of driving a 2A 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.
