The MAX17112ETB+T is a high-performance, step-up, DC-DC converter in 10 pin TDFN package. This converter provides a regulated supply voltage for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs). It 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 IC 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. It is used in LCD monitor panels, notebook and computer displays.
Input voltage range from 2.6V to 5.5V
Operating temperature range from 40°C to +85°C
Maximum IN quiescent current is 0.6mA at VFB = 1.3V, maximum IN shutdown supply current 250μA
