The MAX1747EUP+ is a triple charge-pump DC-DC converter from Analog Devices Inc., specifically designed to provide regulated voltages for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs).
This device converts a +2.7V to +4.5V input supply into three independent output voltages. The primary high-power charge pump generates a regulated output voltage (VOUT) between 4.5V and 5.5V with ±1% regulation. Two low-power charge pumps independently regulate one positive output (VPOS) up to +35V and one negative output (VNEG) down to -35V, utilizing external diode and capacitor multiplier stages.
The MAX1747EUP+ offers an adjustable switching frequency ranging from 200kHz to 2MHz, enabling fast transient response and the use of small ceramic capacitors. It is available in an ultra-thin TSSOP package with a maximum height of 1.1mm, making it suitable for low-profile applications. The converter includes internal power MOSFETs, soft-start, and a power-ready output.
Key features include adjustable outputs, a wide switching frequency range, and an ultra-thin solution without inductors. It is ideal for applications such as TFT active-matrix LCDs, passive-matrix displays, and personal digital assistants (PDAs).
