ETA1611
The ETA1611 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 ETA1611 has an OVP protection feature that prevents the output voltage exceeding the maximum rating of the ETA1611 and the output cap during open conditions.
ETA1611 is available in a space-saving SOT23-6 package.
