MAX77640 - Ultra-Low Power PMIC

Description

The MAX77640/MAX77641 are a low-IQ power solution for applications where size and efficiency are critical.

The device integrates a 3-output single-inductor multiple-output (SIMO) buck-boost regulator, a 150mA LDO, and a 3-channel current-sink driver.

The SIMO operates on an input between 2.7V and 5.

MAX77640/MAX77641 EVALUATION KIT AVAILABLE Ultra-Low Power PMIC with 3-Output SIMO, 150mA LDO, and Power Sequencer General Description The MAX77640/MAX77641 are a low-IQ power solution for applications where size and efficiency are critical. The device integrates a 3-output single-inductor multiple-output (SIMO) buck-boost regulator, a 150mA LDO, and a 3-channel current-sink driver. The SIMO operates on an input between 2.7V and 5.5V. The outputs are independently programmable between 0.8V and 5.25V depending on ordering option. Each output is a buck-boost with glitchless transition between buck and boost operation. The SIMO can support >300mA loads (1.8VOUT, 3.7VIN).
