Deliver Complete Power Management for LTE/WCDMA/GSM/GPRS/EDGE Data Card Based on the New ICERA Platform (E400/E450)
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 flexibility. The linear regulators provide greater than 60dB PSRR, less than 45µV 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.
