The MAX17480 is a triple-output, step-down, fixed-frequency controller for AMD's serial VID interface (SVI) CPU and northbridge (NB) core supplies. The MAX17480 consists of two high-current SMPSs for the CPU cores and one 4A internal switch SMPS for the NB core. The two CPU core SMPSs run 180° out-of-phase for true interleaved operation, minimizing input capacitance. The 4A internal switch SMPS runs at twice the switching frequency of the core SMPS, reducing the size of the external components.The MAX17480 is fully AMD SVI compliant. Output voltages are dynamically changed through a 2-wire SVI, allowing the SMPSs to be individually programmed to different voltages. A slew-rate controller allows controlled transitions between VID codes and controlled soft-start. SVI also allows each SMPS to be individually set into a low-power pulse-skipping state.Transient phase repeat improves the response of the fixed-frequency architecture, reducing the total output capacitance for the CPU core. A thermistor-based temperature sensor provides a programmable thermal-fault output (active-low VRHOT).The MAX17480 includes output overvoltage protection (OVP), undervoltage protection (UVP), and thermal protection. When any of these protection features detect a fault, the controller shuts down. True differential current sensing improves current limit and load-line accuracy. The MAX17480 has an adjustable switching frequency, allowing 100kHz to 600kHz operation per core SMPS, and twice that for the NB SMPS.ApplicationsMobile AMD SVI Core SuppliesMultiphase CPU Core SuppliesNotebook/Desktop ComputersVoltage-Positioned, Step-Down Converters

The MAX17499/MAX17500 current-mode PWM controllers contain all the control circuitry required for the design of wide-input-voltage isolated and nonisolated power supplies. The MAX17499 is well suited for low input voltage (9.5V DC to 24V DC) power supplies. The MAX17500 is well suited for universal input (rectified 85V AC to 265V AC) or telecom (-36V DC to -72V DC) power supplies.The ICs contain an internal error amplifier that regulates the tertiary winding output voltage that is used in primary-side-regulated isolated power supplies. Primary-side regulation eliminates the need for an optocoupler. An input undervoltage lockout (UVLO) is provided for programming the input-supply start voltage and to ensure proper operation during brownout conditions. An open-drain UVLO flag output, with 210μs internal delay, allows the sequencing of a secondary-side controller. The input-supply start voltage is externally programmable with a voltage-divider. A UVLO/EN input is used to shut down the devices. Internal digital soft-start eliminates output voltage overshoot.The MAX17500 has an internal bootstrap UVLO with large hysteresis that requires a minimum 23.6V for startup. The MAX17499 does not have the internal bootstrap UVLO and can be biased directly from a minimum voltage of 9.5V.The switching frequency for the ICs is programmable with an external resistor. The MAX17499A/MAX17500A provide a 50% maximum duty-cycle limit, while the MAX17499B/MAX17500B provide a 75% maximum duty-cycle limit.

The MAX2991 power-line communication analog front-end (AFE) is a state-of-the-art integrated circuit that delivers high integration and superb performance, while reducing the total system cost. The MAX2991 is the first AFE specifically designed for OFDM (orthogonal frequency division multiplexing) modulated signal transmission over power lines. Operating in the 10kHz to 490kHz band, the programmable filters allow compliance with CENELEC, FCC, and ARIB standards using the same device.The MAX2991 transceiver provides two main paths: transmit (Tx) path and receive (Rx) path. The transmit path injects an OFDM modulated signal into the AC or DC line. The transmit path is composed of a digital IIR filter, digital-to-analog converter (DAC), followed by a lowpass filter, and a preline driver. The receiver path is for the signal enhancement, filtering, and digitization of the received signal. The receiver is composed of a lowpass and a highpass filter, a two-stage automatic gain control (AGC), and an analog-to-digital converter (ADC). The integrated AGC maximizes the dynamic range of the signal up to 60dB, while the lowpass filter removes any out-of-band noise, and selects the desired frequency band. The ADC converts the enhanced and amplified input signal to a digital format. An integrated offset cancellation loop minimizes the DC offset.The MAX2991, along with the MAX2990 PLC baseband modem, delivers the most cost-effective data communication solution over power-line networks in the market. The MAX2991 is specified over the -40°C to +85°C temperature range and is available in a 48-pin LQFP package.ApplicationsAutomatic Meter ReadingBuilding AutomationHeating Ventilation and Air Conditioning (HVAC)Home AutomationIndustrial AutomationLighting ControlRemote Monitoring and ControlSecurity Systems/Keyless EntrySensor Control and Data AcquisitionSmart Grid

The MAX31722/MAX31723 digital thermometers and thermostats with an SPI/3-wire interface provide temperature readings that indicate the device temperature.
