AIC1533

www.DataSheet4U.com AIC1533 Triple-Output LCD Power Supply FEATURES One Low Dropout Linear Regulator Dropout Voltage 500mV at 0.3A Output Current Dual Adjustable Charge Pump Up to +30V Positive Output Down to -10V Negative Output Power Up Sequencing and Adjustable Delay time Power-Saving Shutdown Mode (0.1µA typical) Operating Supply Voltage: 12V 1MHz Operation Frequency Internal Current Limit and Thermal Protection built in LDO part Few External Components Required DESCRIPTION AIC1533, composed of dual charge pumps and a regulator, provide three independent regulated voltages designed for using in thin-film transistor (TFT) liquid crystal display (LCD). The main regulator has an adjustable output voltage and a low dropout voltage of 500mV at 300mA load current is performed. The dual charge pumps independently regulate a positive output and a negative output. AIC1533 has thermal shutdown capability and survives a continuous short circuit from output to ground. A unique control scheme minimizes output ripple as well as output capacitance for both charge pump. APPLICATIONS LCD Monitor Panel Module LCD TV Panel Module 1MHz-switching frequency of AIC1533 provides a DataSheet4U.com DataShee low noise, low cost total solution. The device operates up to 15V supply voltage and is available in 14-lead SOP and 16-lead TSSOP package. Analog Integrations Corporation Si-Soft Research Center 3A1, No.1, Li-Hsin Rd.
