RT
Drain of 60V 0.8Ω NDMOS switch and input of H/V regulator.
Source of NDMOS switch and current sense input. Connect a resistor to GND to program the
output current and short circuit thresholds.
Power ground. Must be wired to AGND on PCB.
PWM dimming input. This TTL input enables switching of SW when in high state.
No connection.
Resistor connected between RT and VDD programs the off-time of SW.
Analog ground (0V).
Power supply for all internal circuits. Bypass with a low ESR capacitor to PGND (>0.5μF).
Connect gate of external depletion-mode NFET for high-voltage operation.
