上海钰泰 ETA1621S2G 高效升压转换器IC芯片

　　DESCRIPTION

　　The ETA1621 is a high efficiency step-up converter with an internally integrated 20V/2.8A low side power MOSEFT. It runs with an optimal 1MHz frequency that enables the use of small external components while still providing the best efficiency. Given the 2.8A power FET,ETA1621 is suitable for delivering 0.15-2A output current depending on the Vout/Vin ratio. The incorporated true PWM-Diming feature through EN pin enable one further digitally program the output voltage lower. For maximum protection, the ETA1621 has an OVP protection feature that prevents the output voltage exceeding the maximum rating of the ETA1621 and the output cap during open conditions.

　　ETA1621 is available in a space-saving SOT23-6 package.
