DESCRIPTION (CONT.)
Simple external networks allow for flexible compensation of the current and voltage control loops. In addition,
UCC28180 offers an enhanced dynamic response circuit that is based on the voltage feedback signal to deliver
improved response under fast load transients, both for output over-voltage and under-voltage conditions. An
unique VCOMP discharge circuit provided in UCC28180 is activated whenever the voltage feedback signal
exceeds V
OVP_L
thus allowing a chance for the control loop to stabilize quickly and avoid encountering the over-
voltage protection function when PWM shut-off can often cause audible noise. Controlled soft start gradually
regulates the input current during start-up and reduces stress on the power switches. Numerous system-level
protection features available in the controller include VCC UVLO, peak current limit, soft over-current, output
open-loop detection, output over-voltage protection and open-pin detection (VISNS). A trimmed internal reference
provides accurate protection thresholds and regulation set-point. The user can control low power standby mode
by pulling the VSENSE pin below 0.82 V.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these or any other condition beyond those included under “recommended operating
conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods of time may affect device reliability.
