ETA ETA1617
The ETA1617 is a high efficiency step-up converter with an integrated 40V power MOSEFT. It runs with an optimal 0.8MHz frequency that enables use of small external components while still providing best efficiencies. It has an internal current limit as high as 1A, and it can drive up to 8 LEDs at 60mA output current.DESCRIPTION
FEATURES
The ETA1617 is a high efficiency step-up converter with● an integrated 40V power MOSEFT. It runs with an
● optimal 0.8MHz frequency that enables use of small
● external components while still providing best
● efficiencies. It has an internal current limit as high as 1A,
● and it can drive up to 8 LEDs at 60mA output current.
● The incorporated 18-100KHz true PWM-Dimming
● feature by EN pin can be used to digitally program the
● LED current. For maximum protection, the ETA1617 has an internal OVP protection at 33V to prevent the chip from damages when the LED string is not connected to the output. Up to 89% Efficiency (6 LEDs) Drive up to 8 LEDs with 60mA Drive up to 40 LEDs in total 33V OVP Protection True PWM Brightness Control 200mV Feedback Voltage 1A Current Limit SOT23-6 Package ETA1617 is available in a space-saving SOT23-6 package.
