The MIC2826 is a four output, programmable Power Management IC, optimized for high efficiency power support in Mobile Application Processors, Co-Processors, DSPs, GPS and Media Player chipsets. The device integrates a single 500mA PWM/PFM synchronous buck (step-down) regulator with three Low Dropout Regulators and a 400kHz I2C interface that provides programmable Dynamic Voltage Scaling (DVS), Power Sequencing, and individual output Enable/Disable controls allowing the user to optimally control all four outputs.?The 4MHz synchronous buck regulator features a patented HyperLight Load??(HLL) architecture which minimizes switching losses and provides low quiescent current operation for high efficiency at light loads. Additional benefits of this proprietary architecture are low output ripple voltage and fast transient response throughout the entire load range with the use of small output capacitors, reducing the overall system size.Three high performance LDOs are integrated into the MIC2826 to provide additional system voltages for I/O, memory and other analog functions. Each LDO is capable of sourcing 150mA output current with high PSRR and low output noise. A 2% output voltage accuracy, low dropout voltage (150mV @ 150mA), and low ground current of 116μA (all three LDOs operating) makes this device ideally suited for mobile applications.\n\n \n\n
