产品概述 返回TOPwrR嘉泰姆
The CXLE82118 is a current mode DC/DC converter with
an internal 2.5A, 40V switch specifically designed to
drive LEDs. The CXLE82118 operates as a LED driver in
buck, boost and buck-boost mode. The LED current is
externally programmable with a 120mV sense resistor.
With a 500KHz operating frequency, the external inductor
and input/output capacitors can all be small.
Dimming can be either analog, PWM, or PWM converting
to analog with an external capacitor.
The CXLE82118 is available in TDFN-12L 3x3 and MSOP-10
(FD) package.
