The positive and negative linear-regulator controllers postregulate charge-pump outputs for TFT gate-on and gate-off supplies. Both linear-regulator controllers, as well as the step-up regulator, have supply-sequencing control inputs. The three outputs can be sequenced in any order by selecting the appropriate external components. The MAX1997 features a high-current backplane driver (VCOM). This buffer provides peak currents exceeding 300mA (typ) and requires only a 0.47F output filter capacitor. The MAX1997's two additional linear-regulator controllers can be used to build the gamma reference voltage and a logic supply. |
