ISL78419 - Integrated Automotive TFT-LCD Power Supply Regulator

Features

  • a 1.5A/0.18Ωboost FET with 600kHz/1200kHz switching frequency. The integrated 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 generates a reset signal when t.

DATASHEET ISL78419 Integrated Automotive TFT-LCD Power Supply Regulator FN8292 Rev 3.00 June 27, 2014 The ISL78419 is an integrated power management IC (PMIC) for TFT-LCDs used in central display, rear seat entertainment and virtual dashboards. The device integrates a boost converter for generating AVDD, an LDO regulator for VLOGIC. VON and VOFF are generated by a charge pump driven by the switch node of the boost converter. The ISL78419 also includes a VON slice circuit, reset function, and a high performance VCOM amplifier with a Digitally Controlled Potentiometer (DCP) that is used as a VCOM calibrator. The AVDD boost converter features a 1.5A/0.18Ωboost FET with 600kHz/1200kHz switching frequency.
