GENERAL DESCRIPTION
The ADP5022 is a micro power management unit (micro PMU)
that combines two high performance buck regulators and a low
dropout regulator (LDO) in a tiny 16-ball 2.08 mm × 2.08 mm
WLCSP 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 required. When the MODE pin is set high, the buck reg-
ulators operate in forced PWM mode. When the MODE pin is
set low, the buck regulators automatically switch operating
modes, depending on the load current level. At higher output
loads, the buck regulators operate in PWM mode. When the
load current falls below a predefined threshold, the regulators
operate in power save mode (PSM), improving the light-load
efficiency.
The two bucks operate out-of-phase to reduce the input
capacitor requirement and noise.
The low quiescent current, low dropout voltage, and wide input
voltage range of the ADP5022 LDO extends the battery life of
portable devices. The LDO maintains power supply rejection
greater than 60 dB for frequencies as high as 10 kHz while
operating with a low headroom voltage.
Each regulator in the ADP5022 has a dedicated, independent
enable pin. A high voltage level applied to the enable pin activates
the respective regulator. The default output voltages are factory
programmable and can be set to a wide range of options.
