Multiple-output power-supply controller with integrated PMIC for LCD TVs

Maxim has introduced the MAX17113, a new multiple-output power-supply controller with integrated PMIC and provides a cost-effective power solution for large LCD panels.

The MAX17113 can operate from 8V to 16.5V input voltages and is optimized for LCD TV panel and LCD monitor applications running directly from 12V supplies.

The step-up and step-down regulators feature internal power MOSFETs and high-frequency operation allowing the use of small inductors and capacitors. Both switching 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 protect the step-up and step-down power supplies against fault conditions.

The key features of the MAX17113 are,

Optimized for 10.8V to 13.2V input supply
Selectable frequency (450kHz/600kHz)
Adjustable positive and negative charge-pump regulators
Soft-start and timer-delay fault latch for all outputs
Logic-controlled high-voltage integrated switches with adjustable delay
120mOhm p-channel FET for AVDD sequencing
Input undervoltage lockout and thermal-overload protection

Operating temperature range: -40°C to +85°C

Package: 40-Pin, 5mm x 5mm Thin QFN package
Price: Starts at $1.30 for 1k pieces
