Part Number: LM5022SEPBLDT_NOPB
Hello,
We have designed a boost regulator using LM5022 for 150W load :
Vin = 20 to 48V; Vout = 48V
Vin = 48 to 60V, Vout = Vin.
This works for all the input range except when Vin = 48V. There's a loud humming noise when Vin = 48V for 150W load and output is not stable. Its oscillates between 46 to 50V. I think its because of the slope compensation resistor of 1.5K ohms. Without the 1.5Kohms, the regulator doesnt work for any input range for maximum load. Can you please recommend a correct slope compensation resistor value?
