Frequently Asked Questions
What functions does the UCC28500DWTR integrate?
The UCC28500DWTR integrates a power factor correction (PFC) controller and a PWM post-regulator controller in a single IC. It supports both current-mode and voltage-mode control, has programmable UVLO thresholds (16 V/10 V for VCC and 6.75 V/5.5 V for PWM), and operates over a 10.3 V to 18 V input range, making it a highly integrated solution for two-stage AC-DC power supply designs.
What does UVLO mean and how is it configured on the UCC28500DWTR?
UVLO stands for Under-Voltage Lock-Out, a protection feature that prevents the controller from operating below a minimum supply voltage. On the UCC28500DWTR, the VCC UVLO thresholds are 16 V (turn-on) and 10 V (turn-off), while the PWM UVLO thresholds are 6.75 V (turn-on) and 5.5 V (turn-off). These thresholds help ensure clean startup and controlled shutdown under low-supply conditions.
What package does the UCC28500DWTR come in?
The UCC28500DWTR is housed in a 20-pin SOIC (Small Outline Integrated Circuit) package with JEDEC code R-PDSO-G20. It is lead-free and RoHS-compliant as indicated by the 'Pbfree Code: Yes' specification. The tape-and-reel format (TR suffix) is optimized for high-volume automated assembly using standard pick-and-place and reflow soldering equipment.
What control modes does the UCC28500DWTR support?
The UCC28500DWTR supports both current-mode and voltage-mode PWM control, which can be selected through programming. Current-mode control is the default operating mode and offers inherent cycle-by-cycle current limiting and improved transient response. Voltage-mode control provides more flexibility in compensation network design. This dual-mode capability makes the controller adaptable to a wide variety of power supply topologies.
What are typical applications for the UCC28500DWTR?
Typical applications include desktop and server power supplies, industrial AC-DC adapters, telecom power systems, and energy-efficient converters requiring active power factor correction. The integrated PFC/PWM combination reduces external component count in two-stage power supply designs. The -40°C to 85°C operating range also makes it suitable for demanding industrial environments.
