uP6636Q中文资料High Efficiency PMIC with Dynamic Voltage Management数据手册uPI(UBIQ)规格书

描述 Description

The uP6636Q includes 4 synchronous-rectified buckconverters and 9 linear regulators. With internal lowRDS(ON) switches, the buck converter is capable ofdelivering 1.5A or 2.8A output current over a wide inputvoltage range from 2.7V to 5.3V. Fixed 2.25MHz PWMoperation allows possible smallest output ripple andexternal component size. Dynamic Voltage Scaling (DVS)is supported either by dedicated control pins, or throughI2C interface to optimize the system performance for theprocessor. Other features include internal soft-start, overtemperature,and over-current protections.

The power sequence and reset controller provides poweronreset, software initiated reset, and power cycle resetfor the processor. It also features the watchdog supervisoryfunction. Multiple sleep modes with autonomous sleep andwake-up sequence control are supported.The uP6636Q is available in a space-saving, VQFN6x6-48L package.
