The MAX8688 fully integrated digital power-supply controller and monitor IC works with any existing POL (point-of-load) power supply to provide complete digital programmability. By interfacing to the reference input, feedback node, and output enable, the MAX8688 takes control of the POL to provide functions such as perfect tracking, sequencing, margining, and dynamic adjustment of the output voltage.The MAX8688 offers an accurate 12-bit analog-to-digital converter (ADC) accompanied with two differential amplifiers for accurately monitoring both voltage and current. An integrated 12-bit digital-to-analog converter (DAC) is also available to margin power supplies as well as dynamically adjust the output voltage with 0.2% accuracy over temperature using this closed-loop system. An internal temperature sensor provides an additional level of system monitoring.The user-programmable registers provide flexible and accurate control of time events such as a delay time and transition period, monitoring for overvoltage and undervoltage, overcurrent, reverse-current, overtemperature fault and warning handling. The closed-loop operation is also programmable to make sure the MAX8688 works with any existing POL to provide superior regulation accuracy and accurate margining.The MAX8688 operates using a PMBus™-compliant communication protocol. The device is programmed using this protocol or simply with the use of a free graphic-user interface (GUI) available from the Maxim website that significantly reduces development time. Once the configuration is complete, the results can be saved into an EEPROM or loaded onto the part through the PMBus at power-up. This allows remote configuration of any POL using the MAX8688, replacing expensive recalls or field service. Module current sharing is also supported, since accurate current measurement and fine resolution voltage control are available. The MAX8688 can be programmed with up to 127 distinct addresses to support large systems. The MAX8688 is offered in a space-saving, 24-pin, lead-free 4mm x 4mm TQFN package.ApplicationsDC-DC Modules and POLsHigh-Reliability Infrastructure EquipmentServersTelecom Networking

The MAX12900 is an ultra-low-power, highly integrated 4-20mA sensor transmitter. The MAX12900 integrates ten building blocks in a small package: a wide input supply voltage LDO, two conditioner circuits for pulse-width modulated (PWM) inputs, two low-power, low-drift, general purpose operational amplifiers (op amp) one wide bandwidth, zero-offset drift operational amplifier; two diagnostic comparators, a power-up sequencer with power good output to allow for a smooth power-up, and a low-drift voltage reference.The MAX12900 converts PWM data from a microcontroller into current over a 4-20mA loop with two, three, or four wire configurations.The equivalent to an ultra-low-power, high-resolution, digital-to-analog converter is realized with the combination of two-PWM signals received from a microcontroller, the two conditioner circuits, and an active filter built with the integrated low-power op amp. The outputs of the two conditioner circuits provide a stable PWM amplitude over voltage supply and temperature variation. The wide bandwidth amplifier, in combination with a discrete transistor, converts a voltage input into a current output and allows HART and Foundation Fieldbus H1 signal modulation. The zero-offset operational amplifier and the low-drift voltage reference provide negligible error over wide temperature. The low-power operational amplifier and comparators provide building blocks for enhanced diagnostic features. Supply rail monitoring, output current readback, open circuit and failure detection are a few examples of diagnostic features. All these features, as well as ultra-low-power and high accuracy make the MAX12900 ideal for loop-powered smart sensor transmitters for industrial application.The MAX12900 is available in 5mm x 5mm 32-pin TQFN package and operates over a wide industrial temperature range of -40°C to +125°C.ApplicationsIndustrial Automation and Process ControlLoop-powered 4-20mA Current TransmitterRemote InstrumentationSmart Sensors
