Frequently Asked Questions
What control mode does the UCC3806DW use?
The UCC3806DW uses current-mode pulse width modulation (PWM) control, which provides faster transient response and inherent cycle-by-cycle overcurrent protection compared to voltage-mode control, improving power supply stability and reliability.
What is the switching frequency of the UCC3806DW?
The UCC3806DW operates at a fixed switching frequency of 52kHz, suitable for a wide range of switching power supply topologies including flyback, forward, and push-pull converters used in industrial and telecom power designs.
What is the output drive capability of the UCC3806DW gate drivers?
The UCC3806DW provides dual totem-pole gate drivers rated at 0.5A peak output current each, capable of efficiently driving power MOSFETs and IGBTs in half-bridge, full-bridge, and other multi-switch power converter designs.
What power supply input voltage range does the UCC3806DW support?
The UCC3806DW operates from 8V to 14.5V in standard mode, with the ability to also function in an adjustable mode from 2.5V to 15V, giving designers flexibility for a range of input bus voltages in DC-DC converter applications.
What package does the UCC3806DW use and is it lead-free?
The UCC3806DW is available in a 16-pin SOIC (Small Outline Integrated Circuit) package, a standard surface-mount form factor well-supported by PCB assembly equipment. It is RoHS-compliant and lead-free as indicated by the Pb-free code designation.
