Dual 3 MHz, 1200 mA Buck
Regulators with Two 300 mA LDOs
ADP5034 Data Sheet
FEATURES regulators operate in PWM mode when the load is above a predefined threshold. When the load current falls below a predefined
threshold, the regulator operates in power save mode (PSM),
improving the light load efficiency. Main input voltage range: 2.3 V to 5.5 V
Two 1200 mA buck regulators and two 300 mA LDOs
24-lead, 4 mm × 4 mm LFCSP or 28-lead TSSOP package
Regulator accuracy: ±1.8%
Factory programmable or external adjustable VOUTx
3 MHz buck operation with forced PWM and auto PWM/PSM
