Overview

Description

The MAX17112 is a high-performance, step-up, DC-DC converter that provides a regulated supply voltage for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs). The MAX17112 incorporates current-mode, fixed-frequency (1MHz), pulse-width modulation (PWM) circuitry with a built-in, n-channel power MOSFET to achieve high efficiency and fast-transient response. The input overvoltage protection (OVP) function prevents damage to the MAX17112 from an input surge voltage (up to 24V).

The high switching frequency (1MHz) allows the use of ultra-small inductors and low-ESR ceramic capacitors. The current-mode architecture provides fast-transient response to pulsed loads. A compensation pin (COMP) gives users flexibility in adjusting loop dynamics. The internal MOSFET can generate output voltages up to 20V from an input voltage between 2.6V and 5.5V.

Soft-start slowly ramps the input current and is programmable with an external capacitor. The MAX17112 is available in a 10-pin TDFN package.
