Part details & applications

The MAX8752 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 MAX8752 incorporates current-mode, fixed-frequency, pulse-width modulation (PWM) circuitry with a built-in n-channel power MOSFET to achieve high efficiency and fast transient response. The input supply voltage of the MAX8752 is from 1.8V to 5.5V.

The MAX8752 operates with a switching frequency of 1.2MHz, allowing the use of ultrasmall inductors and low-ESR ceramic capacitors. The current-mode architecture provides fast transient response to the pulsed loads typical of LCD source-driver applications. A compensation pin (COMP) gives users flexibility in adjusting loop dynamics. The 14V internal MOSFET can generate output voltages up to 13V. The internal digital soft-start and current limit effectively control inrush and fault currents.

The MAX8752 is available in a 3mm x 3mm 8-pin TDFN package with a maximum height of 8mm.
