Dual 3 MHz, 800 mA Buck Regulators in WLCSP  
Data Sheet  
ADP5133  
The two bucksoperate outofphase to reduce the inputcapacitor  
requirement and noise.  
FEATURES  
Input voltage range: 2.3 V to 5.5 V  
Two 800 mA buck regulators  
T iny, 1 6 -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  
The regulators in theADP5133 areactivated through dedicated  
enablepins. The output voltagescan be externally set through a  
resistor feedbacknetwork.

The ADP5133 combines two high performance buckregulators  
in a tiny, 16-ball,2mm ×2mm WLCSPto meet demanding  
performance and board space requirements.

The high switchingfrequency ofthe buck regulators enables tiny  
multilayer external components and minimizes the boardspace.  
When the MODEpin is set high, the buckregulators operatein  
forced PWM mode. When the MODEpin is set low and the  
buck regulators operatein PWM mode, the loadcurrent is above  
a predefined threshold. When the load current falls belowa  
predefined threshold, the regulators operate in power save  
mode (PSM), improving the light load efficiency.
