Overview

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 ADP5133 combines two high performance buck regulators in a tiny, 16-ball, 2 mm × 2 mm WLCSP to meet demanding performance and board space requirements.

The high switching frequency of the buck regulators enables tiny multilayer external components and minimizes the board space. When the MODE pin is set high, the buck regulators operate in forced PWM mode. When the MODE pin is set low and the buck regulators operate in PWM mode, the load current is above a predefined threshold. When the load current falls below a predefined threshold, the regulators operate in power save mode (PSM), improving the light load efficiency.

The two bucks operate out of phase to reduce the input capacitor requirement and noise.

The regulators in the ADP5133 are activated through dedicated enable pins. The output voltages can be externally set through a resistor feedback network.
