VSS_P
Connects to dedicated GND for Aout and Bout
Drivers
VDD_P
Connects to dedicated VDD for Aout and Bout
Drivers
VSS
Connects to analog GND
VDD
Connects to analog VDD
BEPOL
Tri-mode input pin to control the polarity of the
ENABLE and BRITE signal
VDDSW
Switchable VDD output controlled by ENABLE
BRITE
Analog/PWM input for brightness control
TRI_C
Connects to external capacitor CTRI
CPOR
Connects an external capacitor CPOR to VDD and
is used for setting power-up reset pulse width.
OLSNS
Analog input to detect open-lamp condition
ENABLE
Used to enable or disable the chip
ISNS
Analog input from lamp current, has built-in 300mv
offset
I_R
Connects to external resistor RI; for bias current
setting for internal oscillator
ICOMP
Current error Amp’s output; connects to external
capacitor CICOMP
CPWM1
Connects to external capacitor CPWM, used for
integrating an external digital PWM signal for
analog dimming
VCOMP
Voltage error Amp’s output; connects to external
capacitor CVCOMP, can be used for soft-start
CPWM2
Connects to external capacitor CPWM, used for
integrating an external digital PWM signal for
analog dimming.
VSNS
Analog input from transformer output voltage
RMP_RST
If SLAVE = “0”, RMP_RST is a CMOS output; if
SLAVE = “1”, it is a CMOS input that locks the
ramp oscillation frequency to the master clock
SLAVE
Input control pin for setting the IC either in Master
or Slave mode; “1” for slave mode and “0” for
master mode.
PHA_SYNC
If SLAVE= “0”, PHA_SYNC is a CMOS output; if
SLAVE = “1”, it is a CMOS input that make the
AOUT/BOUT phase synchronous with the master
FAULT
Digital output to indicate maximum number of lamp
striking attempts has occurred without lamp
ignition.
