The G4 and E4 suffixes were added for ROHS conversion. The
G4 and E4 parts are exactly the same as the original parts
without the G4 or E4 suffix.

For lead-frame-based devices, the RoHS-compliant solution
is backward-compatible with lead-based processes; so the
same part is shipped regardless of whether a unique part
number or a standard part number is ordered.

Lead-frame-based unique part numbers will consist of the
standard part number plus a two-character suffix (usually
E4 or G4, sometimes E3, E6, G3 or G6).

"E" = RoHS-compliant

"G" = Green (RoHS-compliant and no Br/Sb)

UCC2891x High-Voltage Flyback Switcher

Texas Instruments UCC2891x High-Voltage Flyback Switcher is dedicated to isolated flyback power supplies and provides output voltage and current regulation without the use of an optical coupler. The device incorporates a 700V power FET and a controller that processes operating information from the auxiliary flyback winding and from the power FET to provide precise output voltage and current control. The integrated high-voltage current source for a startup that is switched off during device operation and the controller current consumption that is dynamically adjusted allows very low standby power. Control algorithms in the Texas Instruments UCC2891x, combining switching frequency and peak primary current modulation, allow operating efficiencies to meet or exceed applicable standards. Discontinuous conduction mode (DCM) with valley switching is used to reduce switching losses. The maximum switching frequency is 115kHz. Protection features help to keep secondary and primary component stress levels in check across the operating range.
