UC3851DWTR Description

***as Instruments: Programmable Off-Line PWM Controller 18-SOIC 0 to 70

***ical: Current Mode PWM Controller 500kHz 18-Pin SOIC T/R

***ser: PWM Power Supply Controllers Prog, Off-Line PWM Controller

***i-Key: IC OFFLINE CTRLR PWM PROG 18SOIC

***ark: Pulse Width Modulation (PWM) Controller IC; Frequency:450kHz; Power Dissipation, Pd:1W; No. of Pins:18; Operating Temperature Range:0°C to +70°C; Control Mode:Current, Voltage; Leaded Process Compatible:Yes ;RoHS Compliant: Yes

***AS INSTRUM: The UC1851 family of PWM controllers are optimized for off-line primary side control. These devices include a high current totem pole output stage and a toggle flip-flop for absolute 50% duty cycle limiting. In all other respects this line of controllers is pin for pin compatible with the UC1841 series. Inclusion of all major housekeeping functions in these high performance controllers makes them ideal for use in cost sensitive applications.

***ASI: Important features of these controllers include low current start-up, linear feed-forward for constant volt-second operation, and compatibility with both voltage or current mode control. In addition, these devices include a programmable start threshold, as well as programmable over-voltage, under-voltage, and over current fault thresholds. The fault latch on these devices can be configured for automatic restart, or latched off response to a fault.

***AS INSTRUMENTS INC: These devices are packaged in 18-pin plastic or ceramic dual-in-line packages, or for surface mount applications, a 20 Pin PLCC. The UC1851 is characterized for -55°C to +125°C operation while the UC2851 and UC3851 are designed for -40°C to +85°C and 0°C to +70°C, respectively.
