What are the key features of UC2854DWTRG4?
- Current-mode PWM control achieves near-unity power factor correction in boost pre-regulator topologies
- Switching frequency up to 118 kHz enables compact magnetic design for reduced converter size
- 15V to 35V input voltage range (nominal 18V) suits a broad range of offline power supply front-ends
- 16-pin SOIC (R-PDSO-G16) surface-mount package simplifies high-density PCB integration
What is UC2854DWTRG4 used for?
The UC2854DWTRG4 is designed for offline AC-DC power supply pre-regulators where high power factor and low harmonic distortion are required to meet IEC 61000-3-2 standards. It is widely used in industrial power supplies, electronic ballasts for lighting, and UPS front-end stages. Its current-mode PWM architecture ensures stable operation across load variations in continuous conduction mode boost converters.

Frequently Asked Questions
What control mode and switching frequency does the UC2854DWTRG4 support?
The UC2854DWTRG4 uses current-mode pulse width modulation (PWM) control and can switch at frequencies up to 118 kHz. This combination enables fast transient response and the use of smaller inductors and capacitors compared to lower-frequency designs.
What is the input voltage range and quiescent current of the UC2854DWTRG4?
The device operates from an input voltage of 15V minimum to 35V maximum, with a nominal design point of 18V. Its quiescent supply current is just 1.5 mA, helping to minimize standby power loss in the bias supply.
Which package does the UC2854DWTRG4 use and is it RoHS compliant?
It comes in a 16-pin Small Outline IC (SOIC) package, JESD-30 code R-PDSO-G16, supplied on tape and reel. The JESD-609 code e4 confirms it is fully RoHS compliant and lead-free.
What are the typical applications for the UC2854DWTRG4?
Typical applications include front-end boost PFC pre-regulators in AC-DC power supplies for computers and servers, electronic ballasts for fluorescent and HID lamps, industrial motor drives, and uninterruptible power supply (UPS) systems requiring power factor correction per IEC 61000-3-2.
