2A, 24V Step-Up Regulator

DESCRIPTION

The ETA1611 is a high efficiency step-up converter with an

internally integrated 24V 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.
