1
AOUT
Output driver A.
2
VSS_P
Power ground for output drivers only.
3
VSS
Signal ground.
4
AFD_C
Connects to an external cap, CAFD. Forcing to ground or VDD will make the VCO oscillate at approximately
50% of the maximum VCO frequency. Forcing to VDD/2 will make the VCO oscillate at 2x the FVERT
frequency.
5
RAMP_C
Connects to external capacitor CRAMP for setting Direct Drive PWM operating frequency.
6
RAMP_R
Connects to external resistor RRAMP for setting Direct Drive PWM operating frequency.
7
FVERT
Vertical frequency reference digital input. Has internal pull down.
8
PD_CR
Phase Detector Filter. Part of phase lock loop. Connects to external capacitor and resistor network.
9
VCO_C
Connects to external capacitor CVCO.
10
BRT_POS
Brightness control polarity. Has internal pullup. Leave open or pull up to VDD for dimming brightness
proportional to BRITE voltage, connec to ground for brightness inversely proportional to BRITE voltage.
11
BRITE
Analog voltage input for brightness control.
12
DIG_DIM
Digital Dimming Enable internal pullup. Leave open or pull up to VDD for operating in digital dimming
mode. Connect to ground for analog dimming mode.
13
ENABLE
Chip Enable internal pullup. High enables the chip. Low disables.
14
I_R
Current Reference Resistor. External resistor to ground (Ri) determines internal capacitor CICOMP.
15
BRT
Current Error Amplifier non-inverting input.
16
VCOMP
Voltage Error Amplifier output. Connects to external frequency compensation capacitor CVCOMP. Controls
soft-start timing.
17
VSNS
Voltage Error Amplifier inverting input.
18
ICOMP
Current Error Amplifier output. Connects to external frequency compensation capacitor CICOMP.
19
ISNS
Current Error Amplifier inverting input.
20
OLSNS
Open Lamp Sense Input.
21
TRI_C
Connects to external capacitor CTRI for setting strike frequency ramp slope.
22
VDD
23
VDD_P
Dedicated VDD for output buffers only.
24
BOUT
Output driver B.
