ETA1617S2G-单串10颗LED背光驱动器
DESCRIPTION
The ETA1617 is a high efficiency step-up converter with an
internally 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 10
LEDs at 50mA output current. The incorporated 25-100KHz
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 38V to prevent the
chip from damages when the LED string is not connected to
the output.
ETA1617 is available in a space-saving SOT23-6 package
