Preliminary Datasheet LP6283 Power Management ICs for TV / Monitor General Description Features 8V to 14V Supply Input Voltage Range The LP6283 generates all the supply rails for thin-film Current-Mode Boost Regulator transistor (TFT) liquid-crystal display (LCD) panels in TVs 20V 3.5A 0.1 Internal N-MOSFET Programmable Over Current Protection and monitors. It includes boost and buck regulators, VGH Programmable Soft-Start Current-Mode Buck Regulator and VGL charge pump regulators, gate pulse modulator 16.5V 2A 0.15 Internal N-MOSFET (GPM) , HV LDO, voltage detector (XAO) and VCOM OP. Over Current Protection Adjustable Output Voltage from 1.8V to 3.3V The LP6283 supports input voltage from 8V to 14V and is Adjustable VGH Charge Pump optimized for LCD TV panel and LCD monitor Continuous Output Current 50mA Adjustable VGL Charge Pump applications running directly from 12V supply. Continuous Output Current 50mA The boost and buck regulators feature internal power Gate Pulse Modulator 18V to 35V Positive Supply Input MOSFETs and high-frequency operation, allowing the Power-On/Off Sequence Control On-Chip GPM Controller with Adjustable use of small inductors and capacitors, for in a compact Falling Time and Falling Stop Voltage solution. Both switching regulators use fixed-frequency, Voltage Detector (XAO) Adjustable Detecting Voltage (1%) current-mode control architectures, providing fast N-Channel Open-Drain Output load-transient response and easy compensation. VCOM OP 5V to 20V Input Supply Voltage The VGH and VGL charge-pump regulators provide 300mA Output Short-Circuit Current for 1ms supply voltages for the TFT gate driver. Both output 45V/ s Slew Rate 20MHz, 3dB Bandwidth voltages can be adjusted with external resistive voltage HV LDO dividers. 5V to 20V Input Supply Voltage Adjustable Output Voltage (0.5%) Order Information Over Current Protection (60mA) Low Dropout Voltage 0.5V (60mA) LP6283 Selectable Frequency (500kHz/750KHz) External PMOS Isolation Switch Controlled by Gate Drive Signal F: Pb-Free Over Temperature Protection Power On Sequence Control Package Type TQFN 48 Package QVF : TQFN-48 RoHS Compliant and Halogen Free Applications Pb-Free Package LCD TV/Monitor Marking Information Device Marking Package Shipping LP6283 LPS TQFN-48 LP6283 YWX Y: Y is year code.
