Maxim Integrated (MAX1748EUE+T) Display Driver, Triple Output TFT-LCD

Product Overview The MAX1748EUE+T is a triple output TFT-LCD DC-DC converter in 16 pin TSSOP package. It provide regulated voltages required by active-matrix, thin-film transistor (TFT) liquid-crystal displays (LCDs). One high-power DC-DC converter and two low-power charge pumps convert the +3.3V to +5V input supply voltage into three independent output voltages. The primary 1MHz DC-DC converter generates a boosted output voltage (VMAIN) up to 13V using ultra small inductors and ceramic capacitors. The low power BiCMOS control circuitry and the low on-resistance (0.35ohm) of the integrated power MOSFET allows efficiency up to 93%. The dual charge pumps independently regulate one positive output (VPOS) and one negative output (VNEG). IC soft-starts each supply as soon as the previous supply finishes. It is used in TFT active-matrix LCD displays, passive-matrix LCD displays, PDAs, digital still cameras and camcorders. Supply voltage range is 2.7V to 5.5V Operating temperature range from -40°C to 85°C 3 integrated DC-DC converters, internal supply sequencing & internal power MOSFETs 1MHz current-mode PWM boost regulator, up to +13V main high-power output, ±1% accuracy High efficiency of 93%, dual charge-pump outputs, up to +40V positive charge-pump output Down to -40V negative charge-pump output 0.1µA shutdown current, 0.6mA quiescent current, internal soft-start & power-ready output Ultra-small external components Applications Power Management, Portable Devices Product Information No. of Digits: - No. of Segments: - Driver Case Style: TSSOP No. of Pins: 16Pins Supply Voltage Min: 2.7V Supply Voltage Max: 5.5V Interface Type: - Operating Temperature Min: -40°C Operating Temperature Max: 85°C Product Range: - MSL: MSL 1 - Unlimited
