3.3 Power Requirement
3.3.1 HIOVDD, NIOVDD, COREVDD, PLLVDD
The S5U13709P00C100 Evaluation Board is designed to generate HIOVDD, NIOVDD,
COREVDD and PLLVDD from 5V via the S5U13U00P00C100 USB Interface Board. 5V must be
supplied from the S5U13U00P00C100. JP1 on the S5U13U00P00C100 USB Interface Board
should be set to position 2-3. 3.3V power supply is generated by one voltage regulator (U3) and
fixed output. HIOVDD and NIOVDD can be selected 3.3V or 5V using jumper JP9 and JP10.
COREVDD is possible to select HIOVDD, NIOVDD or LDOVDD0. PLLVDD are possible to select
HIOVDD, NIOVDD or LDOVDD1. If use the LDOVDD0 and LDOVDD1, it is external input from
JP1 and JP3. Refer to Table 3-2a and 3-2b on page 9.
3.3.2 Backlight Power Supply for LCD Panel
The S5U13709P00C100 Evaluation Board has an incorporated White LDE Driver Controller
(TPS61161A) for the panel backlight. White LED Driver Controller drives the panel at a constant
current. The S5U13709P00C100 Evaluation Board is possible to change the output current
(20mA, 40mA, 60mA / Max 38V). Please set J1 with the specifications of the panel. Refer to
Table 3-2c on page 9.
