DESCRIPTION
The UCC28600-Q1 is a PWM controller with
advanced energy features to meet stringent
world-wide energy efficiency requirements.
UCC28600-Q1 integrates built-in advanced energy
saving features with high level protection features to
provide cost effective solutions for energy efficient
power supplies. UCC28600-Q1 incorporates
frequency fold back and green mode operation to
reduce the operation frequency at light load and no
load operations.
UCC28600-Q1 is offered in the 8-pin SOIC (D)
package. Operating ambient temperature range is
-40°C to 105°C.

(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 conditions beyond those indicated under “recommended operating
conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltages
are with respect to GND. Currents are positive into, negative out of the specified terminal. Consult Packaging Section of the databook
for thermal limitations and considerations of packages.
