Part Number: LM51561H-Q1 Other Parts Discussed in Thread: LM51561 , LM5156 , UCC28600 , LM25180 Hi
I would like to design a QR-Flyback with LM51561H-Q1 SYNC-PIN.
The pri-Aux power will be the SYNC-single clock.
Will it work?
Could you offer the TI-Tina file…
Part Number: LM51561H Other Parts Discussed in Thread: LM5022 , LM5156H Dear Texas Instruments Support,
I hope this message finds you well. I am currently working on a design project with the specific goal of achieving a power supply average lifespan of…
Part Number: LM51561H Hi,
As far as I understand the LM51561H has 2 enable levels at the UVLO/EN:
@0.5V Vcc is regulated to min(Vin,7V). The controller starts drawing current
@1.5V the controller starts pumping PWM and the converter starts working well…
Part Number: LM51561H Other Parts Discussed in Thread: LM5156 Hi,
I am trying to create SEPIC regulator configuration using LM51561HQPWPRQ1 IC. My input voltage range is 9V to 16V and required output is 9V/300mA.
I have attached 2 simulation circuit with…

Hello HongGyo,
Please explain which problem you have with the increase rise time of the external clock signal. The moment when you get above the threshold is slightly shifted, but as this is the case for all rising edges, I wonder if this is really a…
