PS10 Power Good Clamp
If the active high enabled dc/dc converter used does not have an internal clamp, an external zener diode may be used to pro-
tect the module.

Notes:
1. Under Voltage Shutdown (UV) set to 37V.
2. Over Voltage Shutdown (OV) to 57.8V.
3. Other power good outputs will have the same
configuration as PWGRGD-A for Active High Enabled
Converters.

Typical Application Circuit for a 12V Non-Isolated System
Most FPGAs, Processors, ASICs, and DSPs require sequencing and rail voltage limitation during start-up and power down
sequence of its rails. A typical requirement is: V
DD_CORE must not exceed VDD_IO more than 0.6V and VDD_IO must not ex-
ceed V
IN at any time. This can be accomplished by sequencing the dc/dc converters by the following manner:
Turn On: V
DD_CORE first, VDD_IO second, and VIN last.
Tun-Off: V
IN first, VDD_IO second, and VDD_CORE last.
The Schottky diodes will limit the voltage between the rails to around 0.3V @ 3A during the power-up and power-down
sequence.
Assuming that the /EN pins of the dc/dc converters have no pull-up and have a 1.0V turn-off threshold, the power-down
sequence time delays can be approximated by:
T
PWRGD-C to TPWRGD-B = 1F x 1V / 1mA = 1ms
T
PWRGD-B to TPWRGD-A = (2F-1F) x 1V / 1mA = 1ms
