제품 세부 사항
Flyback Controller, Current Control, UCC28/UCC38 Series, Texas Instruments
The isolated-flyback power supply controller provides Constant-Voltage (CV) and Constant-Current (CC) output regulation to improve transient response to large load steps. Primary-Side Regulation (PSR) eliminates the need for an Optocoupler.
The Texas Instruments UCC2801 family of high-speed, low-power integrated circuits contain all of the control and drive components required for off-line and DC-to-DC fixed frequency current-mode switching mode power supplies with minimal parts count.
100-μA typical starting supply current
500-μA typical operating supply current
Operation up to 1 MHz
Internal soft start
Internal fault soft start
Internal leading-edge blanking of the current sense signal
1-A totem-pole output
70-ns typical response from current-sense to gate drive output
1.5% tolerance voltage reference
Same pinout as UC3842 and UC3842A
