SWITCHED CAP VOLTAGE INVERTER

The MAX8704 high-current linear regulator uses an external n-channel MOSFET to generate low-voltage supplies for notebook computers. This linear regulator delivers an output voltage as low as 0.5V from an input voltage as low as 1.0V. Normally, this low input requirement would make the design of such a regulator very difficult. In this application, the 5V bias supply that is always available in the system powers the MAX8704 driver and control circuitry. The MAX8704 includes a fixed current limit and an adjustable power limit to protect the external MOSFET from overheating. Additionally, the MAX8704 includes an internal thermal limit to prevent damage to the controller and provide remote thermal protection for the external MOSFET. The MAX8704 features an adjustable soft-start function and generates a delayed power-good (PGOOD) signal that signals when the linear regulator is in regulation. The MAX8704 is available in a 10-pin µMAX® package. Applications Desktop Computers Low-Voltage Bias Supplies Notebook Computers Servers V MCH and V CCP CPU Supplies VID Power Supplies

The MAX8709B integrated backlight controller is optimized to drive cold-cathode fluorescent lamps (CCFLs) using a resonant full-bridge inverter architecture. The resonant operation maximizes striking capability and provides near-sinusoidal waveforms over the entire input range to improve CCFL lifetime. The controller operates over a wide input voltage range of 4.6V to 28V with high power-to-light efficiency. The device also includes safety features that effectively protect against many single-point fault conditions including lamp-out and short-circuit faults. The MAX8709B achieves 10:1 dimming range by “chopping” the lamp current on and off using a digital pulse-width-modulation (DPWM) method. The minimum DPWM duty cycle of the MAX8709B is 12.5%. The brightness is controlled with a 2-wire SMBus™-compatible interface. The device directly drives the four external N-channel power MOSFETs of the full-bridge inverter. An internal 5.3V linear regulator powers the MOSFET drivers, the DPWM oscillator, and most of the internal circuitry. The MAX8709B is available in a space-saving 28-pin thin QFN package and operates over a -40°C to +85°C temperature range. Applications LCD Monitors LCD TVs Notebook Computer Displays
