Part Number: WEBENCH-CIRCUIT-DESIGNER Tool/software: i am planing to designing two dc-dc converters using Webbench power designer tool 1) non isolated DC-DC converter specifications is input voltage iminimum 3.3V and maximum 5V, output is 15V and 15A…
Hi Austin,
Austin Do said: or does it mean it stays ENABLE state until disable condition (LOW ~ 35us)?
Yes, this is what it means.
So you can also apply higher switching frequencies than 333kHz.

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…
