3.3 Power Supply
The S5U13781R00C100 reference board is designed to supply VDDCORE (1.5V) and LED back light
power (LED+/LED-) from the 2.7V to 5.5V input of J4-4 (VDD DCDC).
The voltage output of 2.7V to 3.3V from J4-3 (VDDIO) is used for the U4 (S1D13781 Display
Controller) power supply, D2 (LED indicator) and Y1(SG-310SCF 24MHz OSC).
The power for U2 (M25P-16-VMN6P SPI flash memory) is supplied via J1-2 (FLASH-VCC).
3.3.1 VDDCORE
VDDCORE (1.5V) is generated from U1 (BU15TD3WG Voltage regulator) and is used to supply power
to COREVDD and PLLVDD of U4 (S1D13781 Display Controller).
3.3.2 LED Back Light LED+/LED- Power Supply
The LED back light power supply (Maximum voltage between LED+ and LED- is 38V) is generated by
U3 (TPS61161A voltage booster).
The output current is set by J3 as described in Table 3-2, Jumper Settings. Connecting one of J3 3-4, J3 5-
6 or J3 7-8 allows 20mA, connecting any two of them allows 40mA and connecting all of them allows
60mA output, maximum.
