Product Specification
The iML1942 is a highly integrated power management IC for TFT LCD panels. It features fully I2C interface to program various parameters.
The device consists of one current mode boost regulator for AVDD, one synchronous buck converter for VBK1. An optional inverting converter or negative charge pump regulator for VGL with temperature-compensated output, a negative linear regulator for VSS1, an optional boost regulator or charge pump regulator for VGH with temperature-compensated output, a programmable amplifier for VCOM1, a programmable DAC for VOCM2 and 14-channel programmable Gamma amplifiers.
The iML1942 device includes various protection features such as input under-voltage lockout (UVLO) and over temperature shutdown (OTP). The outputs include under voltage protection (UVP), and short circuit protection (SCP).
The iML1942 is available in a WQFN 46 pin 6.5 mm X 4.5 mm with a bottom side exposed thermal pad to provide optimal heat dissipation. The device is rated to operate from –40 to +85°C temperature range.
