Highly-integrated management IC for the latest 3G / 4G smartphones and tablets

Mouser is now stocking the MAX77826 power management IC (PMIC) from Maxim Integrated. The MAX77826 PMIC is a highly-integrated sub-power management IC for the latest 3G and 4G smartphones, tablets and handheld products. It contains a high-efficiency buck regulator, a buck boost regulator, and 15 low dropout regulators (LDOs) to power up peripherals. Housed in a 3mm2 WLP package, the MAX77826 saves board space, allowing designers to add more peripherals. The device provides power on/off control logic and an I2C serial interface to program individual regulator output voltages and on/off control for complete flexibility. The 3A current-mode buck regulator consumes only 22µA quiescent current in normal operating mode and consumes only 8µA in low-power mode, with reduced load capability. The linear LDOs support a remote capacitor feature and provide greater than 70dB rejection ratio (PSRR) and less than 45µVRMS noise. The MAX77826 features I2C-compatible, two-wire serial interface that comprises a bidirectional serial data line (SDA) and a serial clock line (SCL). Additionally, the IC supports SCL rates up to 3.4MHz. The MAX77826 is available in a 49-bump, 3.018 mm × 3.018 mm WLP package.
