Part Number: UC1845A-EP Hi Experts,
Our customer would like to request information on the junction-to-case thermal resistance of UC1845AMDREP. Please provide if available.
Thank you and best regards, Gerald
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…
Part Number: UC1845A-SP I have several questions below relating to setting tspec limits for the free-run oscillator frequency, the COMP offset diodes, and the Err Amp Input Voltage.
1) The oscillator: I have some DVT data from qty 3 UC1845A-SP that shows…
Part Number: UC1845A-SP Hi Experts,
Our customer would like to know if component 5962P8670411VYC uses a purely bipolar technology or, on the contrary, BiCMOS
In the second case, customer would like to know if we have any SEE reports that could share on…
Part Number: UC1845A-SP Hi,
I'm trying to set switching frequency of my flyback converter using UC1845A-SP.
I need to allo %48 duty cycle and I need fsw=300kHz. I know that Ct capacitance value effects minimum duty cycle and Rt resistance should be…

Hi Team,
we are working on a buck application using the IC UC1845A, for 120V to 15V conversion. pls provide us the reference implementation.
Please share us the TINA spice model for…
Part Number: UC1845A Other Parts Discussed in Thread: UC1843A How I can verify the Vout High with source current of 20mA and 200mA? Is possible to have Vout with duty cycle of 100% with pin RT/CT floating or at ground level?
Part Number: UC1845A
Hi,
I am using a UC1845A to control the switching element MOSFET (FCB20N60F) which is used for a typical Flyback Converter circuit. MOSFET's drain is connected to transformer. Rarely MOSFET is not working stable and broke down.…
Part Number: UC1845A-EP Other Parts Discussed in Thread: UC1843A , UC1845A , UC1842A , UC1844A , UC1843A-EP Does the UC1845A-EP support a 1MHz oscillator frequency as shown in Figure 6 of the datasheet?
The title page refers to "500kHz" operation but it…
Part Number: UC1845A-SP Other Parts Discussed in Thread: UC1845
For the UC1845, do we have an equivalent circuit diagram for the Rt/Ct pin internals that is similar to other controllers that use separate Rt & Ct connections? (see example below):
