Part Number: UC1845 Other Parts Discussed in Thread: UC2845 Dear sir,
quick questions:
Q1: what is the difference between UC1845 and UC2845, except for temperature?
Q2: whether we have SOIC package of UC1845 now?
Nice day!
Regards,
Jack
Part Number: UC1845 Hello,
Is there any data regarding the feedback and reference voltages for the UC1845?
Specifically, EOL tolerances for a worst-case analysis. If not anything similar?
Part Number: UC1845 I am trying to use the PSpice model for UC1845. I get an error when running the sim that V3 is missing a value. Is there an updated model available for this component?
Part Number: UC2845AQ Other Parts Discussed in Thread: UC1845 , , UC1845A-EP Tool/software:
Hi Team,
UC2845AQ is rated for 125 Deg but here thermal resistance is higher than UC1845 CDIP and LCC package, How’s that possible?
Also UC1845A-EP is rated…

Hello,
I need to design an isolated, variable output power supply. Input voltage is 15 to 53VDC
The output voltage is 2V to 50V, the output…
Part Number: UC1845 Hi,
The UC1845 datasheet section 8.3.1.4 RT/CT provides a recommended range for timing resistor R_RT (5Kohm-100Kohm) and timing capacitor C_CT (1nF-100nF), so does it mean the recommended maximum oscillating frequency f_OSC is 1.72/(5Kohm…
Other Parts Discussed in Thread: UC1845 Hello. Would anyone happen to have information on what the temperature coefficient of the 1V clamp inside the UC1845 chip is? I need to know if it increases or decreases with temp, and I can't seem to find any concrete…
In my application I must (at times) operate at low duty cycle, output is 500khz (1meg osc). I must operate at 2% duty cycle, which requires 40ns output on-time. The part outputs 0us on time with comp<0.5v, and jumps to about 140ns 0.5v<comp<0.9v.…
Part Number: UC1845A-SP Hi,
Please provide detailed package drawing for the LCCC-20 quickly, and as a .pdf (not autocad). Part # 5962-8670408VXA (uc1845alqmlv), LDC 1915A.
The datasheet for the UC1845A-SP does NOT have the LCCC-20 (FK) package drawing…
Other Parts Discussed in Thread: UC1845 , UC2845 Hi,
We dont find the simulation models for the UC1845/UC2845 in Tina. Do you have any micromodel text fixture for this. Can you please let us know how to simulate this reegulator.
