PMBus COMMAND DETAILS
MFR_PWM_CONFIG_LTC3880
The MFR_PWM_CONFIG_LTC3880 command sets the switching frequency phase offset with respect to the falling edge
of the SYNC signal. The part must be in the OFF state to process this command. Either the RUN pins must be low or
the part must be commanded off. If the part is in the RUN state and this command is written, the command will be
ignored and a BUSY fault will be asserted. Bits 5 and 6 of this command affect the loop gain of the respective channels
which may require modifications to the external compensation network.
BIT
MEANING
7
Reserved, set to 0.
6
If VOUT0 RANGE = 1, the maximum output voltage
for V0 is 2.75V. If RANGE = 0, the maximum output
voltage for V0 is 4.096V.
5
If VOUT1 RANGE = 1, the maximum output voltage
for V1 is 2.75V. If RANGE = 0, the maximum output
voltage for V1 is 5.5V.
4
Share Clock Enable : If this bit is 1, the
SHARE_CLK pin will not be released until
VIN > VIN_ON. The SHARE_CLK pin will be
pulled low when VIN < VIN_OFF. If this bit is 0, the
SHARE_CLK pin will not be pulled low when VIN <
VIN_OFF except for the initial application of VIN.
