Power-Management ICs for
ICERA E400 Platform
General Description
The MAX8982A/MAX8982P/MAX8982X are complete
power-management ICs for the latest LTE/WCDMA/GSM/
GPRS/EDGE data card based on the new ICERA platform
(E400). The MAX8982A operates from a 4.1V to 5.5V
supply and contains four efficient step-down converters,
nine low dropout linear regulators (LDOs) to power all
RF and baseband circuitry, three current regulators with
programmable current up to 24mA and embedded flash
timers, and an I²C serial interface to program individual
regulator output voltages as well as on/off control for flex-
ibility. The linear regulators provide greater than 60dB
PSRR, less than 45FV of output noise, and minimal cross
coupling noise between LDOs.
The MAX8982X/MAX8982P operates from a 2.9V to 5.5V
supply. The MAX8982X has the same features as the
MAX8982A, except it does not have BUCK3, BUCK4,
and LDO8. The MAX8982P has the same features as the
MAX8982A.
All buck converters and LDOs are enabled/disabled by
either I²C or PWR_REQ control signal after power-up.
This feature provides more flexibility in system design.
