The MAX8643 high-efficiency switching regulator delivers up to 3A load current at output voltages from 0.6V to (0.9 × VIN).The IC operates from 2.35V to 3.6V, making it ideal for on-board point-of-load and postregulation applications. Total output error is less than ±1% over load, line, and temperature.The MAX8643 features fixed-frequency PWM mode operation with a switching frequency range of 500kHz to 2MHz set by an external resistor. High-frequencyoperation allows for an all-ceramic capacitor design. The high operating frequency also allows for small-size external components.The low-resistance on-chip nMOS switches ensure high efficiency at heavy loads while minimizing critical inductances, making the layout a much simpler task with respect to discrete solutions. Following a simple layout and footprint ensures first-pass success in new designs.The MAX8643 comes with a high-bandwidth (> 14MHz) voltage-error amplifier. The voltage-mode control architecture and the voltage-error amplifier permit a type III compensation scheme to be utilized to achieve maximum loop bandwidth, up to 20% of the switching frequency. High loop bandwidth provides fast transientresponse, resulting in less required output capacitance and allowing for all-ceramic capacitor designs.The MAX8643 provides two tri-state logic inputs to select one of nine preset output voltages. The preset output voltages allow customers to achieve ±1% output-voltage accuracy without using expensive 0.1% resistors. In addition, the output voltage can be set to any customer value by either using two external resistors at the feedback with 0.6V internal reference orapplying an external reference voltage to the REFIN input. The MAX8643 offers programmable soft-start time using one capacitor to reduce input inrush current.The MAX8643 is available in a lead-free, 24-pin, 4mm x 4mm thin QFN package.For assistance with selecting appropriate capacitors, resistors, and inductors, try our online component selection spreadsheet.ApplicationsASIC/CPU/DSP Core and I/O VoltagesBase-Station Power SuppliesDDR Power SuppliesPOLsRAID Control Power SuppliesTelecom and Networking Power Supplies

The MAX6495–MAX6499 is a family of small, low-current, overvoltage-protection circuits for high-voltage transient systems such as those found in automotive and industrial applications. These devices monitor the input voltage and control an external nMOSFET switch to isolate the load at the output during an input overvoltage condition. The MAX6495–MAX6499 operateover a wide supply voltage range from +5.5V to +72V.The gate of the nMOSFET is driven high while the monitored input is below the user-adjustable overvoltage threshold. An integrated charge-pump circuit provides a 10V gate-to-source voltage to fully enhance the nMOSFET. When the input voltage exceeds the user-adjusted overvoltage threshold, the gate of the MOSFET is quickly pulled low, disconnecting the load from the input. In some applications, disconnecting the output from the load is not desirable. In these cases, the protection circuit can be configured to act as a voltage limiter where the GATE output sawtooths to limit the voltage to the load (MAX6495/MAX6496/MAX6499).The MAX6496 supports lower input voltages and reduces power loss by replacing the external reverse battery diode with an external series pMOSFET. The MAX6496 generates the proper bias voltage to ensure that the pMOSFET is on during normal operations. The gate-to-source voltage is clamped during load-dump conditions, and the p-channel MOSFET is off during reverse-battery conditions.The MAX6497/MAX6498 feature an open-drain, undedicated comparator that notifies the system if the output falls below the programmed threshold. The MAX6497keeps the MOSFET switch latched off until either the input power or the active-low SHDN pin is cycled. The MAX6498 will autoretry when VOVSET falls below 130mV.These devices are available in small, thermally enhanced, 6-pin and 8-pin TDFN packages and are fully specified from -40°C to +125°C.ApplicationsAutomotiveFireWire®IndustrialNotebook ComputersTelecom/Servers/Networking
