Frequently Asked Questions
What control mode does the UCC2807N-1G4 use?
The UCC2807N-1G4 uses current-mode pulse-width modulation (PWM) control. Current-mode control senses the inductor or switch current each cycle to set the duty cycle, providing inherent cycle-by-cycle overcurrent protection and improved transient response compared to voltage-mode control.
What is the input voltage range for the UCC2807N-1G4?
The UCC2807N-1G4 operates with an input voltage ranging from 7.5V minimum to 12V maximum, with a nominal operating voltage of 10V. This range is compatible with common auxiliary power rails used in switching power supplies and industrial power systems.
What package does the UCC2807N-1G4 use?
The UCC2807N-1G4 is housed in an 8-pin PDIP (Plastic Dual In-line Package), JESD-30 code R-PDIP-T8. This through-hole package is widely used for prototyping and service replacement in switching power supply applications, offering easy manual assembly and socketing.
What are typical applications for the UCC2807N-1G4?
Typical applications include flyback converters, forward converters, DC-DC regulators, and off-line switching power supplies where current-mode PWM control is preferred. With its 1A output and 7.5V to 12V supply range, it suits power adapters, industrial control units, and telecom power modules requiring reliable overcurrent protection.
