LCD boost with true shutdown — what this part does
The Maxim MAX8570EUT-T is an LCD boost converter designed to generate the bias voltage for small-format LCD panels. Its distinguishing feature is true shutdown — when the enable pin is pulled low, the output disconnects from the input, eliminating any leakage path through the inductor and diode. This matters for battery-powered handhelds where the display rail must go to zero in sleep mode without a separate load switch.
RoHS non-compliance — plan your assembly line
This part is RoHS non-compliant, meaning the solder terminations contain lead. If your reflow profile or end-product destination requires lead-free assembly (RoHS), this part will not pass. It suits legacy designs with an existing tin-lead solder process, or prototypes where the exemption applies. Confirm your BOM's RoHS exemption status before ordering.
