Frequently Asked Questions
What is the switching frequency range of the UCC2801D?
The UCC2801D supports switching frequencies up to 1000 kHz (1 MHz), allowing designers to use smaller inductors and transformers, reducing overall power supply size and cost in high-frequency DC-DC converter designs.
What control mode does the UCC2801D use and why does it matter?
The UCC2801D uses current-mode pulse width modulation (PWM) control. This technique provides inherent cycle-by-cycle current limiting, improved line transient response, and simpler loop compensation compared to voltage-mode control, making it ideal for demanding power supply applications.
What is the input voltage range of the UCC2801D?
The UCC2801D operates from an input supply voltage of 8.2 V (minimum) to 12 V (maximum), with a nominal operating voltage of 10 V, making it suitable for standard 12 V rail power supply designs in industrial and consumer applications.
What package does the UCC2801D come in and what are common alternatives?
The UCC2801D is available in an 8-Pin SOIC (Small Outline Integrated Circuit) package. Compatible alternatives within the UCC280x family include the UCC2802D and UCC2803D, which differ in oscillator frequency setpoint and UVLO thresholds but share the same footprint.
