Part Number: UC2526 Hi team, I'm facing some difficulty trying to understand this circuit. It involves an error amplifier from UC2526. I want to evaluate its transfer function. However, as stated in the UC2526's datasheet, this is an Operational Transconductance…
Part Number: UC2526 Dear SIr,
I am not getting proper Control PWM Signal in this arrangement.it is controling output volatge of Buck Converter. But getting good output volatge regulation.I have Shorted Shutdown and reset pin through a resistor. i…
Hi Peter,
Can you share your mail ID.
I will share schematic with you.
As you Know i am Using PWM IC UC2526 with reference previous posts
Problem No 1: My PWM Pulses are missing after certain time period. Because i am using reset pin for my…

Part Number: UC2526 Dear Sir,
I am looking for PWM IC.Which will generate frequency in the range from 0 to 15 Hz for Blinking LED light application.
With UC2526 achieved up to 30 Hz. I didn't get PWM signal 30 Hz with R = 150K and C= 20uF.
Kindly…
Hello Wei,
Sorry for my delay response, actually i have checked the whole setup only in open loop, For your information please, if we take Invert er A-PWM and B-PWM means the ckt function properly, but when signal is stopped by UC 2526 means the bottom…
Part Number: UC3854B Other Parts Discussed in Thread: UC2526 Respected sir,
we are doing the EMI/EMC test of our SMPS(1600W) . It is failing at high frequency (Greater than 20 MHz) region during conducted emission test.
We are using PFC Controller…
