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.

Product Detail

The MAX17112 evaluation kit (EV kit) provides a proven design to evaluate the MAX17112 high-performance step-up DC-DC converter, which provides a regulated supply voltage for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs).

The EV kit operates from a DC supply voltage of 4.5V to 5.5V and is configured to operate with a switching frequency of 1MHz. The high switching frequency allows the use of small, surface-mount components. The step-up switching regulator is configured for a 15V output and provides 600mA with a 4.5V input.

Applications

  • LCD Monitor Panels
  • Notebook Computer Displays
