MAX17114 Multi-Output Power Su
max17114 multi-output power supply with vcom amplifier and high-voltage gamma reference for lcd tvs
the max17114 generates all the supply rails for thin-film transistor liquid-crystal display (tft lcd) tv panels operating from a regulated 12v input. it includes a step-down and a step-up regulator, a positive and a negative charge pump, an operational amplifier, a high-accuracy, high-voltage gamma reference, and a high-voltage switch control block. the max17114 can operate from input voltages from 8v to 16.5v and is optimized for an lcd tv panel running directly from 12v supplies.
the step-up and step-down switching regulators feature internal power mosfets and high-frequency operation allowing the use of small inductors and capacitors, resulting in a compact solution. the step-up regulator provides tft source driver supply voltage, while the step-down regulator provides the system with logic supply voltage. both regulators use fixed-frequency current-mode control architectures, providing fast load-transient response and easy compensation. a current-limit function for internal switches and output-fault shutdown protects the step-up and step-down power supplies against fault conditions. the max17114 provides soft-start functions to limit inrush current during startup. in addition, the max17114 integrates a control block that can drive an external p-channel mosfet to sequence power to source drivers.
the positive and negative charge-pump regulators provide tft gate-driver supply voltages. both output voltages can be adjusted with external resistive voltage-dividers. a logic-controlled, high-voltage switch block allows the manipulation of the positive gate-driver supply. the max17114 includes one high-current operational amplifier designed to drive the lcd backplane (vcom). the amplifier features high output current (±200ma), fast slew rate (45v/µs), wide bandwidth (20mhz), and rail-to-rail outputs.
also featured in the max17114 is a high-accuracy, high-voltage adjustable reference for gamma correction.
the max17114 is available in a small (7mm x 7mm), ultra-thin (0.8mm), 48-pin, tqfn-ep package and operates over the -40°c to +85°c temperature range.
