RT9921 converter
integrated multi-channel dc-dc converter.integrated multi-channel dc-dc converter.
high short-circuit current (140mA), fast slew rate (12V/μs), wide bandwidth (12MHz) and rail-to-rail inputs and outputs.
The VGH charge pump controller provides regulate.
The RT9921 includes a high-performance boost regulator, a low dropout linear regulator (LDO), a gate pulse modulator (GPM), a voltage detector, a VCOM buffer (unitygain OPA), and a VGH charge pump controller for activematrix thin-film transistor (TFT.
