ADP5133: Dual 3 MHz, 800 mA Buck Regulators in WLCSP - 1

Dual 3 MHz, 800 mA Buck Regulators in WLCSP 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 0.8 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. Table 1.

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.
