Multiphase, Fixed-Frequency Controller for AMD Hammer CPU Core Power Supplies
General Description
The MAX8707 is a multiphase (3-/4-phase), interleaved, fixed-frequency, step-down controller for AMD Hammer CPU core supplies. Interleaved multiphase operation reduces the input ripple current and output voltage ripple while easing component selection and layout placement. The MAX8707 includes active voltage positioning with adjustable gain and offset, reducing power dissipation and bulk output-capacitance requirements. The MAX8707 is intended for two different notebook CPU core applications: stepping down the battery directly or stepping down the +5V system supply to create the core voltage. The single-stage conversion method allows these devices to directly step down high-voltage batteries for the highest possible efficiency. Alternatively, 2-stage conversion (stepping down the +5V system supply instead of the battery) at higher switching frequency provides the mini.

MAX8709B
High-Efficiency CCFL Backlight Controller with SMBus Interface
General Description
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 safetyfeatures that effectively protect against many single-pointfault conditions including lamp-out and short-circuit faults.
The MAX8709B achieves 10:1 dimming range.

Dual-Phase MOSFET Drivers with Temperature Sensor
General Description
The MAX8702/MAX8703 dual-phase noninverting MOSFET drivers are designed to work with PWM controller ICs, such as the MAX8705/MAX8707, in notebook CPU core and other multiphase regulators. Applications can either step down directly from the battery voltage to create the core voltage, or step down from a low-voltage system supply. The single-stage conversion method allows the highest possible efficiency, while the 2-stage conversion at higher switching frequency provides the minimum possible physical size. Each MOSFET driver is capable of driving 3nF capacitive loads with only 19ns propagation delay and.

Switched-Capacitor Voltage Inverters
_______________General Description
The ultra-small MAX870/MAX871 monolithic, CMOS charge-pump inverters accept input voltages ranging from +1.4V to +5.5V. The MAX870 operates at 125kHz, and the MAX871 operates at 500kHz. Their high efficiency (90%) and low operating current (0.7mA for the MAX870) make these devices ideal for both battery-powered and board-level voltage-conversion applications. Oscillator control circuitry and four power MOSFET switches are included on-chip. A typical MAX870/ MAX871 application is generating a -5V supply from a +5V logic supply to power analog circuitry. Both parts come in a 5-pin SOT23-5 package and .

Alternatively, 2-stage conversion (stepping down the +5V system supply instead of the battery) at higher switching frequency provides the minimum possible physical size. The MAX8707 features dedicated differential currentsense inputs for each phase and includes a fifth pair of current-sense inputs to provide an accurate voltagepositioning slope and average current-limit protection using a single current-sense resistor. The MAX8707 also has two dedicated inputs that provide differential remote voltage sensing. The MAX8707 provides an analog input for setting the suspend voltage and a slew-rate controller for transitions between VID cod.
