Description
Reference voltage output. Nominal voltage is 2.5 V.
Over-voltage protection setting. Refer to formula for OVP in block diagram
on page 2 of this document.
No connection.
Short-circuit protection input.
Reference voltage input for dimming control.
Current sense feedback.
Compensation for the current sense feedback.
Ground.
Tsst ~ 0.2 Csst (Vdd - 5), where Csst is the soft start capacitor value in µF
and Tsst value is in µs.
Gate drive output for the P-MOSFET.
Gate drive output for the N-MOSFET.
Enable input, active high (Vth is about 1.7 V).
