Part Number: LM22677 Other Parts Discussed in Thread: TINA-TI Tool/software: Hi
I was trying to simulate the LM22677 IC in TINA-TI , converting 14V input to 5V. I used the same values as given by the calculator but still couldn't get exact output so…
Part Number: LM22677 On a development board, I have two LM22677 buck converters for two different voltage levels (adjustable at 12V, fixed at 5V). As per the datasheet section 7.3.4, the RT/SYNC pins of the two connectors are pulled low with 1k resistors…
Part Number: LM22677 Tool/software: Hi,
I have a problem with my design using the LM22677-ADJ buck converter that appears to be sporadic. The design uses 3 of these buck converters on a board, bucking 26.5V down to 19V, 12V, and 5V. Typical output current…
Part Number: LM22677 Hello,
I am wondering if you could help me sort out an issue I'm having with a power calculation.
The datasheet for the LM22677 is showing that the ThetaJA for the part is 22°C/W. Is there a specification for the ThetaJC?
Our…
Part Number: LM22677 Hi Team,
Our customer tried to simulate the LM22677(ADJ) in Webench with the specifications below but the simulated reported an error that the design cannot be created. However, using the specifications from the evaluation module…
Part Number: LM22677 Other Parts Discussed in Thread: LM73605
In our safety critical system we have to perform a MTBF / FIT-Rate calculation. Therefore I'm often using the data from the TI-Website: http://www.ti.com/quality/docs/estimator.tsp

Part Number: LM22677LM22677 Short circuit Issue,
During the cost issue, Cin and Cout All use electrolytic capacitor (Not Low ESR capacitor),
And Doing Short circuit test from continuous 24V power to VIN then 100Hz PWM control single to EN pin (CV…
Part Number: LM22677 In the datasheet for LM22677 it details how two IC's can be connected together in self-synchronization mode. Is it possible to self-synchronize three of these IC's? If so, how would it be done?
Thanks
Part Number: LM22677 The datasheet for the LM22677-ADJ mentions how "A maximum value of 10 kΩ is recommended for the sum of RFBB and RFBT to maintain good output voltage accuracy" (page 15), while the design guide ( www.ti.com/.../snva556.pdf) suggests…
Part Number: LM22677 Hi Team,
my customer put a 100nF cap on EN pin and hope it will make stable.
but they found the EN pin will vibrate and the vibration range follow cap.
the cap bigger will cause vibration range higher.
could you check…
