    MIC23156 - 1.5A, 3MHz Synch Buck Regulator with HyperLight LoadВ® and I2C Control
    Docket ↓
    1.5A, 3MHz Synchronous Buck Regulator
    with HyperLight LoadВ® and I2C Control for
    Dynamic Voltage Scaling General Description Features The MIC23156 is a high-efficiency 1.5A synchronous buck
    regulator with HyperLight Load mode and dynamic
    voltage scaling control through I C. HyperLight Load
    provides very high efficiency at light loads and ultra-fast
    transient response. The ability to dynamically change the
    output voltage and maintain high output voltage accuracy
    make the MIC23156 perfectly suited for supplying
    processor core voltages. An additional benefit of this
    proprietary architecture is very low output ripple voltage
    throughout the entire load range with the use of small
    output capacitors. Fast mode plus I C provides output
    voltage and chip enable/disable control from standard I C
    bus with I C clock rates of 100kHz, 400kHz, and 1MHz. Input voltage: 2.7V to 5.5V Up to 1.5A output current
    2 1MHz I C-controlled adjustable output
    -VOUT = 0.7 to 2.4V in 10mV steps High output voltage accuracy (±1.5% over temperature) Fast pin–selectable output voltage Programmable soft-start using external capacitor Ultra-low quiescent current of 30µA when not switching Thermal-shutdown and current-limit protection Safe startup in to pre-biased output Stable with 1µH output inductor and 2.2µF ceramic ...
