Power Management IC
General Description
The MAX77826 is a subpower management IC for the
latest 3G/4G smartphones and tablets. The MAX77826
contains a high-efficiency BUCK regulator, a BUCK
BOOST regulator and 15 LDOs to power up peripherals.
The MAX77826 also provides power on/off control logic
and an I2C serial interface to program individual regulator
output voltages and on/off control for complete flexibility.
The linear regulators support a remote cap feature and
provide greater than 70dB PSRR and less than 45µVRMS
The MAX77826 features I2C-compatible, 2-wire serial
interface that comprises a bidirectional serial data line
(SDA) and a serial clock line (SCL). The MAX77826 sup-
ports SCL clock rates up to 3.4MHz.
