MAX8698C, Rev08
High Efficiency, Low IQ, PMIC with Dynamic Voltage Management
for Samsung Application Processor S5PC100
General Description
The MAX8698C power management ICs are optimized for devices using Samsung S5PC100® processors,
including smart cellular phones, PDAs, internet appliances, and other portable devices requiring substantial
computing and multimedia capability and low power consumption.
The MAX8698C integrates 12 high-performance low-operating-current power supplies along with management
functions. Regulator outputs include three step-down DC-DC outputs, 8 linear regulators, an always-on
RTCLDO and a backup charger. Step-down DC-DC converter outputs include a 1.8V for memory and two serial-
programmed and GPIO controlled outputs to separately power both the processor core and processor internal
memory. The processor core and internal memory outputs feature dynamic voltage management and default to
1.2V for processor core and 1.2V for internal memory(Default are off during power up). Additional functions
include on/off control for outputs, low-battery detection, a 60ms reset output, and a two-wire I2CTM serial
interface.
All Step-down DC-to-DC outputs are able of running at a switching frequency of up to 4MHz, minimizing the size
of the external components. They utilize a proprietary hysteretic PWM control scheme that switches with nearly
fixed frequency. Input voltage range is from 2.7V to 5.5V allowing a 1-cell Li-Ion, 3-cell NiMH, or a 5V input. The
MAX8698C are available in 42-pin 3.53mm x 3.15mm x 0.64mm WLP package.
