FEATURES
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 Ч 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 modes BUCK1/BUCK2: output voltage range from 0.8 V to 3.8 V LDO1/LDO2: output voltage range from 0.8 V to 5.2 V LDO1/LDO2: input supply voltage from 1.7 V to 5.5 V LDO1/LDO2: high PSRR and low output noise Dual 3 MHz, 1200 mA Buck Regulators with Two 300 mA LDOs ADP5034
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. Table 1. Family Models

Power for processors, ASICS, FPGAs, and RF chipsets Portable instrumentation and medical devices Space constrained devices GENERAL DESCRIPTION
The ADP5034 combines two high performance buck regulators and two low dropout (LDO) regulators. It is available in either a 24-lead 4 mm Ч 4 mm LFCSP or a 28-lead TSSOP package. The high switching frequency of the buck regulators enables tiny multilayer external components and minimizes the board space. When the MODE pin is set to high, the buck regulators operate...
