e)
Panel Power Sequencing ( PANEL_ PW12,3) ( Pin 16, 18) : The MTV312 has two dedicated outputs
VDDCTRL1 and 2 ( Pin32 and Pin3) to control LCD power sequencing once data and control signals
are stable.
f)
Panel interface (Pin73~94) : The RTD2013 driver interface is highly programmable. It supports dual bus /
dual port for XGA drivers.
6.1.2
Power Regulator AIC1563 (U2),AIC1739-25CX(U10) : The AIC1563 is a monolithic control IC containing
the primary functions required for DC to DC converters. The device consists of an internal temperature
compensated reference, comparator, controlled duty cycle.
Oscillator with an active current sense circuit. Desired output voltage are determined by the equation,
Volt = 1.25 ( 1 + R11 / R12), In this case, the output voltage are 3.3Volts
The AIC1563 is a low dropout positive adjustable regulator with minimum of 1A output current capability.
So it is well suited for 2.5 V Regulator
.
6.1.3
Power Regulator AIC1739-25CX(U10) : The AIC1739-25CX is a monolithic control IC containing the
primary functions required for DC to DC converters. The device consists o f an internal temperature compensated
reference, comparator, controlled duty cycle.
Oscillator with an active current sense circuit. Desired output voltage are determined by the fixed output function,
the output voltage are 2.5 Volts for scaler power.
