Note: Timer time calculation equation
Timer time t-tim2 is the time until PG pin inversion (from low to high) after the PWM-CS pin trigger.
t-tim2 can be set using the following approximate equation.
t-tim2
The time at which both the PFC and PWM functions are stopped by this timer can be calculated
using the following approximate equation.
t-tim2' = 1.65
