Part Number: PMP8944 Hi Team,
We have designed the same PMP8944 in our project.
We have tested the device with nominal room ambient temperature condition(around 28 deg C to 30 deg C).
When we measured the temperature of the components, the secondary side…
Part Number: PMP8944 Other Parts Discussed in Thread: PMP Hi Team,
We are following the same PMP8944 design, but our input voltage range is slightly different i.e, 20VDC-32VDC.
When we are applying the input voltage greater than 30V(31V or 32V), the Q6…
Part Number: PMP8944 Hi team,
In PMP8944 reference deign, the connector J7 is used for shutdown purpose i think.
We are making the same design setup and we short that connector.
After removing the short also we didn't get any output.
What may be the…
Part Number: PMP8944 Other Parts Discussed in Thread: UCC2897 Hi team,
In PMP8944 reference design 200kHz is the operating frequency.
But UCC2897 has the minimum operating frequency as 225kHz.
Will it create any problem ?

Part Number: PMP8944 Hi Team,
Kindly help on this below (related to PMP8944 schematics)
1. What is the maximum current through the resistor R5, since it is present in the input side, its ratings is just 1/2W, is this enough?
2.what is the current through…
Part Number: PMP8944 Hi,
IN PMP8944 , L3 is rated with 60mA but the transformer aux current rating is 100mA.
With this low current rating is the inductor work properly?
Part Number: PMP8944 Hi Team,
In PMP8944 self driven synchronous rectification is used.
May i know the reason, what is the need of the components Q1, Q2, Q9, Q8 and some discrete components(like R3, R63, D1, D3 etc)in this design.
Can you please explain…
Part Number: PMP8944 Other Parts Discussed in Thread: UCC2897A Hi,
Kindly share the below details,
1.Operating temperature of reference design board PMP8944 .
2. Is there any fan or heat-sink details for PMP8944
Part Number: PMP8944 Hi Team,
PMP8944 has the input range of 18VDc to 30VDC.
If we extend the input voltage upto 32VDC, is there any changes in transformer and any other thing?
