UC2841DW 評級和評論

Y***h

Exactly 30 days to samara, exactly 30 days. These are good indicators. Lowering converters came as expected in antistatic sachets, but bluetooth module without it. All the same, this is a customs check. In the additional review i will write about the performance of the devices. Now five stars to the seller and my recommendations.

UC2841DW 描述

***as Instruments: 32-V, 1-A , 0.5MHz off-line PWM controller , -20C to 85C 18-SOIC -20 to 85

***ical: Current Mode PWM Controller 1A 500kHz 18-Pin SOIC Tube

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

***ark: Pulse Width Modulation (PWM) Controller IC; Frequency:450kHz; Power Dissipation, Pd:1W; No. of Pins:18; Operating Temperature Range:-40°C to +85°C; Control Mode:Current, Voltage; Number of PWM Outputs:1; Output Current:400mA ;RoHS Compliant: Yes

***ASIN: The UC1841 family of PWM controllers has been designed to increase the level of versatility while retaining all of the performance features of the earlier UC1840 devices. While still optimized for highly-efficient boot-strapped primary-side operation in forward or flyback power converters, the UC1841 is equally adept in implementing both low and high voltage input DC to DC converters. Important performance features include a low-current starting circuit, linear feed-forward for constant volt-second operation, and compatibility with either voltage or current mode topologies.

***as Instruments (TI): In addition to start-up and normal regulating PWM functions, these devices include built in protection from over-voltage, under-voltage, and over-current fault conditions with the option for either latch-off or automatic restart.

***AS INSTRUM: While pin compatible with the UC1840 in all respects except that the polarity of the External Stop has been reversed, the UC1841 offers the following improvements:

***INS: 1. Fault latch reset is accomplished with slow start discharge rather than recycling the input voltage to the chip.

***as Instruments Inc.: 2. The External Stop input can be used for a fault delay to resist shutdown from short duration transients.

***AS: 3. The duty-cycle clamping function has been characterized and specified.

***AS INSRUMENTS: The UC1841 is characterized for -55°C to +125°C operation while the UC2841 and UC3841 are designed for -25°C to +85°C and 0°to +70°C, respectively.
