ETA1617
40V Boost Converter for LED Driver / TFT Bias / USB Power
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.
