What are the key features of UCC2570D?
- Dual-mode operation supporting both voltage-mode and current-mode PWM control for design flexibility
- Narrow 10 V to 13 V input voltage range optimized for regulated bus power supply topologies
- 14-pin SOIC (R-PDSO-G14) small outline package enabling compact PCB layouts in space-constrained power modules
- Low quiescent current consumption suited to energy-efficient switching converter designs
What is UCC2570D used for?
The UCC2570D is well-suited for off-line and DC-DC switching power supply designs where voltage-mode or current-mode PWM control is required at input voltages of 10 V to 13 V. It targets applications such as telecom DC-DC converters, industrial power modules, and embedded power rails in networking equipment that benefit from a compact 14-pin SOIC footprint. Designers in battery-backed systems and distributed power architectures choose this controller for its flexibility in operating in either control mode without redesign.

Frequently Asked Questions
What input voltage range does the UCC2570D support and how does that constrain power supply design?
The UCC2570D accepts an input voltage from 10 V to 13 V with a nominal operating point of 11 V. This narrow window targets applications powered from regulated 12 V rails such as telecom bays, industrial control backplanes, and embedded server power architectures, ensuring stable PWM operation within that range.
How does the UCC2570D current-mode feature compare with its voltage-mode PWM control?
In voltage-mode the UCC2570D modulates duty cycle based on output voltage feedback alone, while current-mode adds an inner current sense loop that improves transient response and simplifies slope compensation. Switching frequencies up to several hundred kHz are achievable in both modes, letting designers select loop stability versus noise tradeoffs for their specific converter topology.
Which switching converter topologies are compatible with the UCC2570D?
The UCC2570D suits forward, flyback, and half-bridge DC-DC converters operating from a 10 V to 13 V input bus. Its 14-pin SOIC package provides dedicated gate drive output pins capable of sourcing current to drive MOSFETs, making it compatible with both isolated and non-isolated switching stages in the 5 W to 50 W power range.
Is the UCC2570D RoHS compliant and what package does it ship in for automated assembly?
The UCC2570D is not marked as lead-free (Pbfree Code: No) and ships in a 14-pin small outline SOIC package (JESD-30 code R-PDSO-G14). The 14-pin SOIC body measures approximately 8.65 mm in length and is compatible with standard SMT pick-and-place assembly, making it straightforward to integrate on high-volume PCB production lines.
