Figure 42. SM1/SM2 Converter
The TPS65820 SM1 and SM2 buck converters can be set to operate only in PWM mode or to switch
automatically between PFM and PWM modes. The average load current is monitored, and the PFM mode is set
if the average load current is below the threshold IPFM(ENTER). When in PFM mode the load current is also
monitored, and the PWM mode is set when the load current exceeds the threshold IPFM(LEAVE). The thresholds for
automatic PFM/PWM switching are calculated as shown in Equation 6 for the SM1 converter, the same
thresholds apply to the SM2 converter by replacing VIN_SM1 by VIN_SM2 :
The automatic switching mode is enabled via the control bits PFM_SM1 and PFM_SM2 on I2C registers
SM1_SET1 and SM2_SET1.
I2C registers enable setting the output voltage slew rate, when transitioning from one programmed voltage to a
new programmed voltage value. These events can be triggered by a new output voltage selection or by switching
from a low power mode (standby) to a normal operating mode. During a transition, the output voltage is stepped
from the currently programmed voltage to the new target voltage. The slew rate from the initial voltage to the final
voltage can be selected using I2C registers, SM1_SET2 and SM2_SET2, ranging from 0.24 mV/
s to 15.36
mV/
s for the SM1 converter and 0.48 to 30.72 mV/s for the SM2 converter. If the slew rate is set to OFF, the
output voltage goes from the current value to the programmed value in a single step.
During the transition to standby mode the Power Good comparators are disabled.
