    MIC23250
    4MHz Dual 400mA Synchronous Buck
    Regulator with HyperLight Load™ General Description Features The MIC23250 is a high efficiency 4MHz dual 400mA Input voltage: 2.7V to 5.5V
    HyperLight Load™
    synchronous buck regulator with HyperLight Load™ mode. Dual output current 400mA/400mA
    HyperLight Load™ provides very high efficiency at light Up to 94% peak efficiency and 85% efficiency at 1mA
    loads and ultra-fast transient response which is perfectly 33µA dual quiescent current
    suited for supplying processor core voltages. An additional 1µH inductor with a 4.7µF capacitor
    benefit of this proprietary architecture is very low output 4MHz in PWM operation
    ripple voltage throughout the entire load range with the use
    of small output capacitors. The fixed output MIC23250 has Ultra fast transient response
    a tiny 2mm x 2mm Thin MLF® package that saves Low voltage output ripple
    precious board space by requiring only 6 additional 20mVpp in HyperLight Load™ mode
    external components to drive both outputs up to 400mA 3mV output voltage ripple in full PWM mode
    each. 0.01µA shutdown current
    The device is designed for use with a 1µH inductor and a Fixed output:10-pin 2mm x 2mm Thin MLF®
    4.7µF output capacitor that enables a sub-1mm height. Adjustable output:12-pin 2.5mm x 2.5mm Thin MLF®
    The MIC23250 has a very low quiescent current of 33µA –40°C to +125°C junction temperature range
    with both outputs enabled and can achieve over 85%
    efficiency at 1mA. At higher loads the MIC23250 provides a
    constant switching frequency around 4MHz while providing
    Applications
    peak efficiencies up to 94%. Mobile handsets ...
