The MAX8685 family charges high-voltage photoflash capacitors quickly, while limiting peak drain from the battery, through an efficient flyback switching regulator. The internal n-channel MOSFET improves efficiency over competing bipolar designs by lowering switch-voltage dropout. An integrated insulated gate bipolar transistor (IGBT) driver enables flash discharge and reduces external component count. The device includes an open-drain active-low DONE output to indicate when the photoflash voltage has reached regulation. The device automatically refreshes the output voltage every 16s, thus efficiently maintains the capacitor charge level with minimum battery drain. The MAX8685A/MAX8685F feature an undervoltage input (UVI) monitor. UVI monitors the supply voltage and suspends switching if the input voltage drops below a programmed threshold. The MAX8685A/MAX8685F also feature a voltage-monitor output that provides a scaled replica of the output voltage. The voltage-monitor output is used for interfacing with a microprocessor's internal A/D converter to assist in implementing red-eye reduction. The MAX8685C/MAX8685D, with fixed peak-primary current limits of 1A and 1.6A, respectively, are offered in a 2mm x 3mm, 8-pin TDFN package. The MAX8685A/MAX8685F, with resistor-programmable current limits of up to 2A (max) and 2.6A (max), respectively, are offered in a 3mm x 3mm, 14-pin TDFN package. All devices operate over the -40°C to +85°C temperature range. Applications Cell-Phone Cameras Digital Cameras Film Cameras Personal Media Players

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.
