ZY7015 Datasheet, PDF (25/34 Pages) Power-One – 3V to 13.2V Input 0.5V to 5.5V Output

ZY7015 15A DC-DC Intelligent POL Data Sheet
3V to 13.2V Input • 0.5V to 5.5V Output
The POL powering the output V1 (Ch3 in the picture)
executes the regular turn-off. Since both V1 and V3
have the same delay and slew rate settings they will
continue to turn off and on synchronously every
130ms as shown in Figure 46 until the condition
causing the undervoltage is removed. The POL
powering the output V2 continues to ramp up until it
reaches its steady state level.
130ms is the interval from the instant of time when
the output voltage ramps down to zero until the
output voltage starts to ramp up again. Therefore,
the 130ms hiccup interval is guaranteed regardless
of the turn-off delay setting.
