MAX77680
Description
The MAX77680/MAX77681 is a 3-channel single-inductor multiple-output (SIMO) buck-boost regulator that regulates three independent rails using only 3μA of quiescent current (IQ). The SIMO improves battery life by replacing inefficient LDOs while being petitive in efficiency to traditional single-output bucks.
The SIMO operates on a input supply 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 >300m A loads (1.8VOUT, 3.7VIN).
The device integrates a flexible power sequencer (FPS) to control power-up/down order of each output. The default output voltages and sequence can be programmed at the factory. An I2C serial interface is used to further configure the device.
The MAX77680/MAX77681 is available in a 30-bump wafer-level package (WLP). Total solution size is only 15.5mm2. For a similar product with...
