产品概述 返回TOP
The CXLE8858B is a high efficiency step-up converter with an internally integrated 22V power MOSEFT. It runs with an optimal 1MHz frequency that enables the use of small external components while still providing the best efficiency. It can drive up to 2A output current. The incorporated true PWM-Diming feature through EN pin enable one further digitally program the output voltage lower. For maximum protection, the CXLE8858B has an OVP protection feature that prevents the output voltage exceeding the maximum rating of the CXLE8858B and the output cap during open conditions.
CXLE8858B is available in a space-saving SOT23-6 package.
