Product Details

The MAX77826 is a subpower management IC for the latest 3G/4G smartphones and tablets. The MAX77826 contains a high-efficiency BUCK regulator, a BUCK BOOST regulator and 15 LDOs to power up peripherals. The MAX77826 also 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 linear regulators support a remote cap feature and provide greater than 70dB PSRR and less than 45µVRMS noise.

The MAX77826 features I²C-compatible, 2-wire serial interface that comprises a bidirectional serial data line (SDA) and a serial clock line (SCL). The MAX77826 supports SCL clock rates up to 3.4MHz.

Applications

  • GSM, GPRS, EDGE, CDMA WCDMA, and LTE Smartphones and Tablets
