Frequently Asked Questions

What control method does UC3826DW use and how does it improve converter performance?

UC3826DW uses current-mode PWM control, which samples the inductor current every switching cycle to regulate the duty cycle. This approach provides inherent cycle-by-cycle overcurrent limiting, reduces audiosusceptibility by more than 20 dB compared to voltage-mode control, and simplifies compensation of the power stage feedback loop in flyback and forward topologies.

What input voltage range does UC3826DW support, and which power supply topologies suit it best?

UC3826DW operates from 10 V to 20 V input, with a nominal design point at 12 V. It is best matched to isolated forward converters, push-pull stages, and half-bridge topologies in 12 V bus power architectures common in telecom shelves and industrial rack-mount equipment delivering 5 V or 3.3 V rails at up to 250 W.

How much gate-drive current can UC3826DW source and sink, and what MOSFET gate charges does that support?

UC3826DW can source and sink up to 250 mA of peak gate-drive current. This is sufficient to charge a MOSFET gate with up to 50 nC of gate charge in under 200 ns, enabling switching frequencies of 200 kHz to 500 kHz with standard n-channel power MOSFETs in 40 V to 100 V voltage classes.

What package does UC3826DW use, and are lead-free versions available?

UC3826DW is housed in an SOIC-24 wide-body package with 1.27 mm pitch leads. The D suffix denotes the standard SOIC package. Texas Instruments offers Pb-free variants that comply with RoHS directives, compatible with lead-free solder reflow profiles peaking at 260 °C per IPC/JEDEC J-STD-020.
