TFT LCD Step-Up DC-DC Converter
General Description
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 dis-
plays (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 typi-
cal 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 cur-
rent 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.
