UCC3800DTR General Description

The UCC3800DTR is a part of the UCC280x family of high-speed, low-power integrated circuits that are designed for off-line and DC-to-DC fixed frequency current-mode switching mode power supplies. With minimal parts count, this device contains all the control and drive components required for efficient power supply operations

Key Features

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
