High-Performance, Step-Up, DC-DC Converter
General 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 currentmode, 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-smal...
