To increase design flexibility and reduce system power consumption, the MAX8982A/MAX8982X allow system designers to program individual output voltages and enable/disable all regulators using the I2C interface or the dedicated control input (PWR_REQ). These PMICs also feature three current regulators with eight dimming current options (up to 24mA) and an embedded flash timer. All LDOs include programmable voltage options and offer greater than 60dB PSRR, less than 45microvolts of output noise, and minimal cross-coupling noise between the LDOs.
The MAX8982A operates from a 4.1V to 5.5V supply, and the MAX8982X operates from 2.9V to 5.5V supply. Both devices are offered in a 3.75mm x 3.20mm, 42-bump wafer-level package (WLP) and are fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range. Pricing starts at $2.85 (1000-up, FOB USA).
