Datasheet Summary
5.5V, 6A Single Synchronous Buck Converter
General Description
The SY2A23006 synchronous buck converter has integrated power MOSFETs, an input voltage range of 2.8V to 5.5V, a configurable output voltage from 0.6V to VIN, and a maximum load current capability of 6A. Under light load conditions, it can operate in either pulse width modulation (PWM) mode or pulse frequency modulation (PFM) mode. The soft-start time and 1.8MHz-3MHz switching frequency can be adjusted using external ponents.
The SY2A23006 also provides power good indication, undervoltage lockout (UVLO), short-circuit protection, cycle-by-cycle current limit protection, and thermal shutdown.
The SY2A23006 is available in a 2mm×3mm-9 pin QFN package.
