Description

The MAX77640/MAX77641 are a low-IQ power solutionfor applications where size and efficiency are critical. Thedevice integrates a 3-output single-inductor multiple-output(SIMO) buck-boost regulator, a 150mA LDO, and a3-channel current-sink driver.The SIMO operates on an input between 2.7V and 5.5V.The outputs are independently programmable between0.8V and 5.25V depending on ordering option. Each outputis a buck-boost with glitchless transition between buckand boost operation. The SIMO can support >300mAloads (1.8VOUT, 3.7VIN).The 150mA LDO provides ripple rejection for noise-sensitiveapplications. The current sinks can be programmedto blink LEDs in custom patterns. The device integratesa power sequencer to control power-up/down order ofeach output. Default output voltages and sequence orderare factory-programmable. An I2C serial interface furtherconfigures the device.The MAX77640/MAX77641 are available in a 30-bumpwafer-level package (WLP). Total solution size is 16mm2.For a similar product with a battery charger, refer to theMAX77650.Design Solution: Choose a Tailored SIMO PMIC for Your Portable Design ›ApplicationsAction Cameras, Wearable/Body CamerasHearables: Bluetooth Headphones and EarbudsInternet of Things (IoT) DevicesWearables: Fitness, Health, and Activity Monitors
