ISL97653A Data Sheet September 7, 2010 FN6367.3 5-Channel Integrated LCD Supply Features The ISL97653A represents a fully integrated supply IC for 5V to 14V Input Supply LCD-TV applications. With an input operating range of 4V to Integrated 4.4A Boost Converter 14V, both commonly used LCD-TV input supplies, 5V and Integrated V Charge Pump and V Slice Circuit 12V, are supported. An A supply up to 20V is generated ON ON VDD by a high-performance PWM BOOST converter with an Integrated V Charge Pump Output OFF integrated 4.4A FET. V is generated using an integrated ON Integrated 2.5A Buck Converter charge pump with on-chip diodes and can be modulated using an on-chip V slice control circuit. V is generated using LDO Controller for an Additional Logic Supply ON OFF an integrated charge pump controller. Additionally, the chip High Voltage Stress (HVS) Test Mode allows for two logic supplies. A buck regulator with an included 2.5A high side switch is used for the main logic Thermal Shutdown output and an internal LDO controller can be used to generate 40 Ld QFN (6mmx6mm) Package a second logic LDO output. Pb-Free (RoHS Compliant) To facilitate production test, an integrated HVS circuit is included which can provide high voltage stress of the LCD Applications panel. LCD-TVs An on-board temperature sensor is also provided for system Industrial/Medical LCD Displays thermal management control. Pinout The ISL97653A is packaged in a 40 Ld 6mmx6mm QFN package and is specified for operation over the -40C to ISL97653A (40 LD 6X6 QFN) +105C temperature range.
