MAX77348A規(guī)格書(shū)詳情
General Description
The MAX77348 is an ultra-low quiescent current, noninverting
buck-boost converter capable of supporting up
to 3.5W output power. The device employs a unique
control algorithm that seamlessly transitions between
the buck, buck-boost, and boost modes, minimizing
discontinuities and subharmonics in the output voltage
ripple.
The MAX77348 is ideal for a system handling less than
3.5W output power from a single cell Li-Ion battery and
requiring high system efficiency with precise voltage
control. The MAX77348’s low-noise operation makes it
optimum to supply power for RF system power, ear bud
applications, and other portable audio systems.
Built-in undervoltage lockout (UVLO), output active
discharge, and thermal shutdown protection ensures
safe operation under abnormal operating conditions.
The MAX77348 is available with a highly configurable
I2C serial interface. The device is available in 16-bump,
1.77mm x 2.01mm, 0.4mm pitch WLP package.
