It came quickly. We haven't tried the case yet. Thank you!

Didn't pack very well. I bought three of them, three of them put on your side and wrapped a little. When I first bought one of them, it was a little funny. Like there's no shortage of packing. I haven't tested yet.

UC3842D8TR Description

***as Instruments: Single ended 500KHz current mode PWM controller with 16V/10V UVLO 100% duty cycle, 0C to 70C 8-SOIC 0 to 70

***et Europe: Current Mode PWM Controller 1A 8-Pin SOIC T/R

***ser: PWM Power Supply Controllers Current-Mode PWM Controller

***ical: UCx84x Current-Mode PWM Controllers

***i-Key Marketplace: UC3842 CURRENT-MODE PWM CONTROLL

***ark: Pulse Width Modulation (PWM) Controller IC; Frequency:450kHz; Power Dissipation, Pd:650mW; No. of Pins:8; Operating Temperature Range:0°C to +70°C; Control Mode:Current; Leaded Process Compatible:Yes; Number of PWM Outputs:1 ;RoHS Compliant: Yes

***ASI: The UCx84x series of control integrated circuits provide the features that are necessary to implement off-line or DC-to-DC fixed-frequency current-mode control schemes, with a minimum number of external components. The internally implemented circuits include an undervoltage lockout (UVLO), featuring a start-up current of less than 1 mA, and a precision reference trimmed for accuracy at the error amplifier input. Other internal circuits include logic to ensure latched operation, a pulse-width modulation (PWM) comparator that also provides current-limit control, and a totem-pole output stage that is designed to source or sink high-peak current. The output stage, suitable for driving N-channel MOSFETs, is low when it is in the off state.

***AS INST: The UCx84x family offers a variety of package options, temperature range options, choice of maximum duty cycle, and choice of turnon and turnoff thresholds and hysteresis ranges. Devices with higher turnon or turnoff hysteresis are ideal choices for off-line power supplies, while the devices with a narrower hysteresis range are suited for DC-DC applications. The UC184x devices are specified for operation from –55°C to 125°C, the UC284x series is specified for operation from –40°C to 85°C, and the UC384x series is specified for operation from 0°C to 70°C.
