Maxim Integrated MAX1513

The MAX1513 includes an additional linear-regulator controller and a high-performance buffer amplifier. The MAX1513/MAX1514 can operate from 2.7V to 5.5V input supplies and provide overload protection with timer delay latch on all the regulated outputs. The step-up regulator controller drives an external Nchannel MOSFET to generate the regulated supply voltage for the panel source-driver ICs.

GENERAL DESCRIPTION

FEATURES

♦ 2.7V to 5.5V Input Supply Range ♦ Input-Supply Undervoltage Lockout ♦ Current-Mode Step-Up Controller Fast Transient Response to Pulsed Load High Efficiency Lossless Current Sensing 430kHz/750kHz/1.5MHz Switching Frequency ♦ Linear-Regulator Controllers for VGON, VGOFF ♦ Linear-Regulator Controller for Logic Supply ♦ High-Performance Buffer Amplifier (MAX1513 Only) ♦ Additional Linear-Regulator Controller (MAX1513 Only) ♦ Power-Up Sequence and VGON Delay Control ♦ VMAIN, VGON, VGOFF, VGAMMA Shutdown Control ♦ Timer-Delay Fault Latch for All Outputs ♦ Thermal-Overload Protection MAX1513/MAX1514 The MAX1513/MAX1514 provide complete power-supply solutions for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs). Both devices include a high-performance step-up regulator controller, three linear-regulator controllers, and an adjustable delay block for startup sequencing. Its current-mode control architecture provides fast transient response to pulsed loads.
