Dual 3 MHz, 1200 mA Buck

Regulators with Two 300 mA LDOs

ADP5034

Data Sheet

regulators operate in PWM mode when the load is above a pre-

defined threshold. When the load current falls below a predefined

threshold, the regulator operates in power save mode (PSM),

improving the light load efficiency.

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 × 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

Space constrained devices

The two bucks operate out of phase to reduce the input capaci-

tor requirement. The low quiescent current, low dropout voltage,

and wide input voltage range of the ADP5034 LDOs extend the

battery life of portable devices. The ADP5034 LDOs maintain

power supply rejection greater than 60 dB for frequencies as

high as 10 kHz while operating with a low headroom voltage.

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 × 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 in

forced PWM mode. When the MODE pin is set to low, the buck

Regulators in the ADP5034 are activated through dedicated

enable pins. The default output voltages can be externally set in

the adjustable version, or factory programmable to a wide range

of preset values in the fixed voltage version.
