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).
The 150mA LDO provides ripple rejection for noise-sensitive applications. The current sinks can be programmed to blink LEDs in custom patterns. The device integrates a power sequencer to control power-up/down order of each output. Default output voltages and sequence order are factory-programmable. An I2C serial interface further configures the device.
The MAX77640/MAX77641 are available in a 30-bump wafer-level package (WLP). Total solution size is 16mm2. For a similar product with a battery charger, refer to the MAX77650.
