Device Overview
The VDAP1000 is a true single-chip solution for Netbook TFT-LCD panels. It features a full function LVDS tim-
ing controller (TCON), fully integrated power management, and a 4/2 channel LED driver.
The integrated TCON is embedded with a single pixel LVDS receiver and a 6-pair mini-LVDS transmitter. The
low voltage swing of the mini-LVDS transmitter minimizes EMI and power consumption, while offering a 6-bit
output and a barrage of key features. The integrated TCON supports WXGA resolution (1366x768) and other
resolutions with EEPROM.
The integrated power management blocks support all the required panel voltages. It features a boost regula-
tor for the source driver, a charge pump regulator for VGL, a charge pump for VGH, an LDO for the TCON core,
and an amplifier to drive the VCOM plane.
The integrated 4-channel white LED driver includes a 45V power MOSFET and supports up to 48 LEDs (with
VF=3.6V max). The string current is adjustable up to 25 mA per channel. Dimming is controlled by SMBus or
directly by PWM.
This device is offered in a 104-ld 5.5 x 11 x 0.85mm MLF (QFN) package, and tested over the temperature range
of 0°C to +70°C.
