Datasheet Analog Devices ADP5133

Dual 3 MHz, 800 mA Buck Regulators in WLCSP ADP5133 Data Sheet
FEATURES The two bucks operate out of phase to reduce the input capacitor
requirement and noise. Input voltage range: 2.3 V to 5.5 V
Two 800 mA buck regulators
Tiny, 16-ball, 2 mm × 2 mm WLCSP package
Regulator accuracy: ±1.8%
Factory programmable or external adjustable VOUTx
3 MHz buck operation with forced PWM and auto PWM/PSM
modes
BUCK1/BUCK2: output voltage range from 0.6 V to 3.8 V The regulators in the ADP5133 are activated through dedicated
enable pins. The output voltages can be externally set through a
resistor feedback network.
