Frequently Asked Questions

What is the input voltage range and gate drive current of the Texas Instruments UC28025DWRG4?

The UC28025DWRG4 operates from 9V to 30V input with a nominal 15V supply, and provides up to 1.5A of gate drive current. This combination allows it to directly drive external power MOSFETs in SMPS topologies including flyback, forward, and push-pull converters without additional gate driver stages.

Can the UC28025DWRG4 be configured for current-mode control in addition to voltage-mode operation?

Yes, the UC28025DWRG4 can be configured in peak current mode or average current mode control in addition to standard voltage-mode PWM control. This flexibility allows designers to implement multiple control strategies in a single 16-pin SOIC device, adapting the controller to various SMPS protection and regulation requirements.

Which power conversion applications benefit most from the UC28025DWRG4 in SOIC-16 packaging?

The UC28025DWRG4 in its 16-pin SOIC package suits telecom rectifiers, industrial DC-DC converters, and UPS precharge circuits where 9V to 30V input, 1.5A gate drive strength, and PWM control precision are needed. Its compact SOIC-16 footprint and tape-and-reel format simplify high-volume automated PCB assembly.
