The MAX20363 is an ultra-low quiescent current, non-inverting buck-boost converter with 500mA output current capability. The MAX20363 is intended for applications that require long run times while also demanding bursts of high current. The device employs a proprietary control algorithm that seamlessly transitions between buck, buck-boost, and boost modes, minimizing discontinuities and subharmonics in the output voltage ripple. The low 1.8V input voltage allows the device to be powered from a variety of sources such as lithium ion rechargeable and lithium primary batteries. The MAX20363 is designed to minimize inductance and capacitance requirements to keep the overall solution size as small as possible.
The MAX20363 is optimized for powering optical photoplethysmogram (PPG) systems. The ultra-fast dynamic voltage scaling (DVS) capability allows the device to transition quickly between output voltages and enable in-frame scaling of LED supply voltage. Additionally, the low output ripple and fast, predictable transient response maximizes the signal-to-noise ratio (SNR) of high-performance optical PPG analog-front-end (AFE).
The MAX20363 is available in an 18-bump, 2.43mm x 1.25mm WLP package, with 0.4mm pitch.
