Note 1

If register BUCK4_MODE = 10 (synchronous) then the buck operates in PFM mode for VBUCK < 0.7 V.

For complete control of the buck mode (PWM versus PFM) use BUCK4_MODE = 00.

Note 2

Minimum tolerance 35 mV.

Note 3

Generated from internal 6 MHz oscillator and can be adjusted by ±10 % via register OSC_FRQ, see

Section 8.14.

Note 4

For short durations to meet peak current requirements IOUT can be operated at up to 10 % higher than

the specified maximum operating condition. The part should not be operated in this mode for extended

periods and is not guaranteed for continuous operation.

Note 5

Auto-mode is not recommended for new designs, see Section

8.7.6.
