Frequently Asked Questions
Which power-supply topologies can use UC3526DWG4 as the PWM controller?
UC3526DWG4 is a voltage-mode PWM switching controller intended for switch-mode power supplies, operating from 8 V to 35 V input rails.
What operating-voltage checks matter before selecting this controller?
Designers should confirm the available bias rail stays within the 8 V to 35 V input range and supports the internal 5 V reference needs.
How should layout teams account for the package style?
The fetched data identifies an SOIC-18 small-outline package, so the PCB should reserve an 18-pin footprint with suitable routing for controller pins.
Which procurement details help confirm the correct TI variant?
Buyers should match the UC3526DWG4 ordering code, SOIC-18 package, 1-function switching-controller role, and RoHS-compliant e4 material code where required.
