Description
designations are for use with bridge
topologies to distinguish between
half-cycles.
The VRSEN and BVRSEN options
allow a PWM output to be set high
after detection of the falling
transition of the rectification
voltage.

3: t2 even cycle
4: t1 odd cycle
5: t2 odd cycle
6: t1 delay
7: t2 delay
8: VRSEN neg. edge

select. t1 and t2 refer to the
modulated edges created by the
ramp. When using TE modulation,
t1 is fixed at time 0 and t2 is
modulated. When using LE
modulation, t2 is fixed at T
switch
(or
0.5 * T
switch
and T
switch
for bridge
topologies) and t1 is modulated.
When using dual0edge modulation,
t1 and t2 are centered around 0.5 *
T
switch
(or 0.25 * T
switch
and 0.75 *
T
switch
for bridge topologies) and
both are modulated. Odd and even
cycle designations are for use with
bridge topologies to distinguish
between half-cycles.
