Referring to the application example shown in Figure 3 and Figure 4, Table 3 describes the settings made.
Table 3: SKYPER ® 12 PV | Application example | Settings
Function Configuration Remark Chapter
Active clamping Disabled Disabled by connecting the pins
CLMP_IN_TOP and CLMP_IN_BOT to
the corresponding PWR_GND pins. 5.6
Bidirectional error
(=HALT) Disabled Disabled by connecting the pin
nERR_IN to pin PWR_VS. 4.7
Dynamic short circuit
protection (DSCP) Enabled at both output
channels Enabled by connecting the pins
VCE_IN_TOP and VCE_IN_BOT to the
corresponding collectors of the
semiconductors through R
VCE_TOP
,
D
VCE_TOP
and R
VCE_BOT
, D
VCE_BOT
.
DSCP configuration via pins
CFG_VCE_TOP and CFG_VCE_BOT.
5.5
Dead time generation Disabled Disabled by connecting pin CFG_IDT to
pin PWR_VS. 5.2
Error mode In case of any secondary
side error condition the
event will be reported at
the pin nERR_OUT. The
driver turns-off the
affected output
immediately and the
second output with the
next turn-off signal at
the corresponding input.
Both outputs remain
blocked until the error
state is reset . Selected by connecting pin CFG_ERR to
pin PWR_VS. 5.1
Error propagation
delay time 700ns (typical value) Fixed value. 5.1
External error Disabled at both
secondary sides. Disabled by connecting the pins
nERR_IN_TOP and nERR_IN_BOT to
the corresponding PWR_VS pins. 5.1
Filter Analogue Selected by connecting pin CFG_FLT to
pin PWR_GND. 5.3
Interlock Disabled Disabled by connecting pin CFG_IDT to
pin PWR_VS. 5.2
Jitter ±3ns (typical value) Selected by connecting the pin
CFG_FLT to pin PWR_GND. 4.5
Short pulse
suppression (SPS) 200 ns (typical value) Selected by connecting pin CFG_FLT to
pin PWR_GND. 5.3
Undervoltage lockout
(UVLO) Always active on primary
and secondary side - 5.4
