Power Management IC

General Description

Beneﬁts and Features

● Compact Total Solution Size Allows More Peripheral

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

Devices in Smartphones and Tablets

• 3A High-Eﬃciency BUCK Regulator

• DVS (Dynamic Voltage Scaling) Through HS I C

• ±1% (typ) Output Voltage DC Accuracy

• Low Power Mode

and an I C serial interface to program individual regulator

• 2A BUCK BOOST Regulator

• 15 Linear Regulators with Remote Cap

output voltages and on/off control for complete flexibility.

The linear regulators support a remote cap feature and

• 3 NMOS LDOs (V

Range: 0.6V to 2.1875V

OUT

provide greater than 70dB PSRR and less than 45µV

noise.

RMS

with 12.5mV Step)

• 1 x 150mA

• 1 x 450mA

• 1 x 600mA

The MAX77826 features I C-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.

• 6 PMOSLV LDOs (V
