Frequently Asked Questions
What control modes does UC28023DW support, and how do they affect inductor current sensing in a DC/DC converter?
UC28023DW supports peak current mode, average current mode, and voltage mode PWM control. In peak current mode, the controller samples inductor current at each switching cycle, typically limiting peak current to values set by a 1 V reference threshold. Average current mode integrates the sensed current over multiple cycles, improving output regulation by less than ±2% load variation across a 9 V to 12 V input range.
Which power supply topologies are best matched to UC28023DW operating at a 15 V nominal input?
UC28023DW at 15 V nominal input is best suited for flyback, forward, and push-pull converter topologies common in 50 W to 300 W industrial power supplies. Its PWM frequency can be programmed via an external resistor-capacitor network, typically set between 50 kHz and 500 kHz, allowing transformer size optimization while keeping switching losses within the 16-pin SOIC package thermal budget.
How does UC28023DW compare to a single-mode voltage-mode controller when designing a 100 W telecom power supply?
UC28023DW offers a significant advantage over single-mode voltage-mode controllers in 100 W telecom power supplies because its current-mode options provide inherent cycle-by-cycle overcurrent protection at thresholds below 1.5 A peak, eliminating a separate current-limit circuit. This reduces the BOM by at least 2 components and shrinks board area by approximately 30 mm², while the 9 V to 12 V input range accommodates standard 12 V bus variations found in telecom shelf architectures.
