UC2842AQ: Ceramic Output Capacitors

Veerasamy Vasudevan
Intellectual 390 points
Part Number: UC2842AQ

Hi,

We are using UC2842AQ in Two switch Forward converter Topology - Vin = 32, Vout = 12, Transformer ratio 1:2, Load 14.13A, Freq 150KHz.

We are operating the Regulator at Current Mode. The regulator would always be in CCM because of Synchronous rectification at the secondary side of the MOSFET. 

We would like to use only Low ESR (<5mohm) Ceramic Capacitors at the output (50 X 10uF). Would this cause any stability issues? Is it necessary to have Tantalum capacitor with high ESR for stability? Can we do with only Ceramic Capacitors, as long as we have sufficient capacitance to have better Load step response?

Regards,

Veerasamy
