The device integrates a boost converter for generating AVDD, an LDO for VLOGIC. VON and VOFF are generated by a charge pump driven by the switch node of the boost. The ISL97649A also includes a VON slice circuit, reset function, and a high performance VCOM amplifier with DCP (Digitally Controlled Potentiometer) that is used as a VCOM calibrator. The AVDD boost converter features a 1.5A/0.18boost FET with 600/1200kHz switching frequency. The logic LDO includes a 350mA FET for driving the low voltage needed by external digital circuitry. The gate pulse modulator can control the gate voltage up to 30V, and both the rate and slew delay times are selectable. The supply monitor gen...
