APW7255
Two Channel Regulators and Three Channel Buck Converters PMIC
Features
General Description
Wide Input Operating Range: 2.9V~5.5V
The APW7255 is a two P-channel low dropout linear regu-
Three Synchronous Buck Regulators for SoC
lator and three synchronous buck converter which needs
-Adjustable Output with 1500mA Output for Core input voltage from 2.9 to 5.5V.
Power
Synchronous buck converter with integrated high side
-Adjustable Output with 1000mA Output for and low side power MOSFET. It is equipped with an
Memory Power
automatic PSM/PWM mode operation. At light load , the
-Adjustable Output with 1000mA Output for IC operates in the PSM mode to reduce the switching
System Power
losses. At heavy load, the IC works in PWM mode.
-1.5MHz Switching Frequency
-High Efficient up to 93%
Low dropout linear regulator delivers current up to 300mA
Tow Low-Dropout Linear Regulators for Sensor: to set output voltage, and it also can work with low ESR
-Adjustable 300mA Output High PSRR, Low Noise
-Adjustable 300mA Output High PSRR, Low Noise
ceramic capacitors. Typical dropout voltage is only 240mV
at 300mA loading.
Thermal-Overload Protection
Power-OK Indicator after CH2 Ready
TQFN3x3-20 Package
Lead Free Green Devices Available (RoHS
Compliant)
The APW7255 is equipped with Power-on-reset, shut-
down control, soft start, over-temperature and current-
limit into a single package to protect the device against
wrong logic control and over-temperature and current
over-loads.
The APW7255 available TQFN3x3-20 provides a very
compact system solution external components and PCB
area.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines Greento mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
