The boost and buck regulators have a selectable 450kHz/600kHz switching frequency and feature internal 20V power MOSFETs. The boost regulator delivers output voltages up to 20V from an 8V to 16.5V input while achieving > 85% efficiency; the buck regulator has an adjustable 1.5V to 5V output. The integrated charge-pump regulators provide the TFT gate-driver supply voltage. A pFET is included for AVdd sequencing, thus eliminating the need for an external pFET in series with the input supply.
The MAX17113 is available in a 5mm x 5mm, 40-pin TQFN package and is fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range. Prices start at $1.30 (1000-up, FOB USA).
