Chapter 4 Technical Description
4.1 Power
4.1.1 Power Requirements
The S5U13517P00C100 evaluation board requires an external regulated power supply (3.3V / 0.5A). The power is
supplied to the evaluation board through pin 34 of the CN1 header, or pin 5 of the P2 header.
The green LED '3.3V Power' is turned on when 3.3V power is applied to the board.
4.1.2 Voltage Regulators
The S5U13517P00C100 evaluation board has an on-board linear regulator to provide the 2.5V power required by
the S1D13517 Display Controller. It also has a step-up switching voltage regulator to generate adjustable 6~24V,
which can be used to power the LED backlight on some LCD panels.
4.1.3 S1D13517 Power
The S1D13517 Display Controller requires 2.5V and 3.0~3.6V power supplies.
2.5V power for COREVDD and PLLVDD is provided by an on-board linear voltage regulator.
IOVDD can be in the range of 3.0~3.6V. When J4 is set to the 1-2 position, IOVDD is connected to 3.3V. If a
different voltage is required for IOVDD, set JP4 to the 2-3 position and connect the external power supply to pin 32
of connector CN1.
