GENERAL DESCRIPTION

The ADP5024 combines two high performance buck regula-

tors and one low dropout (LDO) regulator in a small, 24-lead,

4 mm × 4 mm LFCSP 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, the buck

regulators operate in PWM mode when the load current is above

a predefined threshold. When the load current falls below a pre-

defined threshold, the regulator operates in power save mode

(PSM), improving the light load efficiency.

The two bucks operate out of phase to reduce the input capacitor

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

wide input voltage range of the LDO extends the battery life of

portable devices. The ADP5024 LDO maintains power supply

rejection greater than 60 dB for frequencies as high as 10 kHz

while operating with a low headroom voltage.

Regulators in the ADP5024 are activated though dedicated

enable pins. The default output voltages can be either externally

set in the adjustable version or factory programmable to a wide

range of preset values in the fixed voltage version.
