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.
