Product Details
The step-up and step-down regulators feature internal power MOSFETs and high-frequency operation allowing the use of small inductors and capacitors, resulting in a compact solution. Both switching regulators use fixed-frequency current-mode control architectures, providing fast load-transient response and easy compensation. A current-limit function for internal switches and output-fault shutdown protect the step-up and step-down power supplies against fault conditions. The MAX17113 provides soft-start functions to limit inrush current during startup. The MAX17113 provides adjustable power-up timing.
The positive and negative charge-pump regulators provide TFT gate-driver supply voltages. Both output voltages can be adjusted with external resistive voltage-dividers. The switch control block allows the manipulation of the positive TFT gate-driver voltage.
A series p-channel MOSFET is integrated to sequence power to AVDD after the MAX17113 has proceeded through normal startup, and provides True Shutdown™.
The MAX17113 is available in a small (5mm x 5mm), low-profile (0.8mm), 40-pin thin QFN package and operates over a -40°C to +85°C temperature range.
