2 2.4mm C BST 2 1.3mm EVALUATION KIT AVAILABLE Click here for production status of specific part numbers. MAX77640/MAX77641 Ultra-Low Power PMIC with 3-Output SIMO, 150mA LDO, and Power Sequencer General Description Benefits and Features The MAX77640/MAX77641 are a low-I power solution Compact, High-Efficiency Power Solution Q for applications where size and efficiency are critical. The 3-Output Single-Inductor Multiple-Output (SIMO) device integrates a 3-output single-inductor multiple-out- Buck-Boost Regulator put (SIMO) buck-boost regulator, a 150mA LDO, and a 150mA LDO 3-channel current-sink driver. 3-Channel Current-Sink Driver Flexible Power Sequencing The SIMO operates on an input between 2.7V and 5.5V. GPIO and Reset Output The outputs are independently programmable between 0.8V and 5.25V depending on ordering option. Each out- 3-Output SIMO Extends Battery Life put is a buck-boost with glitchless transition between buck 2.7V to 5.5V Input Voltage Range from Single Cell and boost operation. The SIMO can support >300mA Li-Ion loads (1.8V , 3.7V ). 0.8V to 5.25V Output Voltage Range (Table 1) OUT IN Supports >300mA loads (1.8V , 3.7V ) OUT IN The 150mA LDO provides ripple rejection for noise-sen- Improves Overall System Efficiency while Reducing sitive applications. The current sinks can be programmed Size to blink LEDs in custom patterns. The device integrates Maintains Regulation without Dropout unlike a power sequencer to control power-up/down order of Traditional Bucks each output. Default output voltages and sequence order Glitchless Buck-Boost Operation 2 are factory-programmable. An I C serial interface further configures the device. Low Quiescent Current 300nA Shutdown Current The MAX77640/MAX77641 are available in a 30-bump 5.6A Operating Current (3 SIMO Channels and 2 wafer-level package (WLP). Total solution size is 16mm .
