ARUNA KUMAR ;

I was following up on this power program.

Can you send me an e-mail on the program progress and production status?

SLTA055 is a filter reference design application note. All capacitor formulas are based upon design critera for input and output capacitors when calculating switching regulator minimum capacitance requirement.

HI Ken:

The PTB78560 isolated converter minimum input voltage is 18V with input voltage range 18V to 60V.

Ifx this application does not require isolation, then PTN78020W at 5Vout and 10.5Vin can be used.

If isolation is required, then the discrete solution can use the LM5020.

Hello Tom,

My email address is dannycheng80@gmail.com

If it is possible, can you also send me the reliability report for the C66 DSP (TMX320C6672CYP and TMS320C6678CYPA)?

Thank you.

The reaon for the maximum limit of (-) remote sense limit is to insure stability in this ground circuitry.

We have no power modules to meet these requirements for either input voltage or output voltage.

Tom Guerin — Wed, 27 Mar 2013 14:45:00 GMT

Chandana Bhat :

I reviewed section 1 and section 2 for Turbo trans (Rtt=0Ω) .

Section 3 has a comment about the output ceramic capacitance required for PTH08T230W

Section 1 .The capacitance with low ESR>10mΩ( 25A current step ) 8298uF 13* 680 uF (T530D687M003A(1)E010 with ESR = 10 m ohm) is confirmed for the 40mV transient response.

Section 2. The capacitance with low ESR>6mΩ( 12A current step ) 1546 uF with 5* 330 uF ((T530D337M006A(1)E006 with ESR= 6 m ohm) is confirmed for the 450mV transient response.

Section 3. PTH08T230W requires a minimum of 200uF ceramic capacitance on the output bus. Increase 47 uF(C3216X5R0J476M) x4 to meet this requirement.

The capacitance with low ESR>6mΩ( 4.5A current step ) 7* 330 uF (T530D337M006A(1)E006 with ESR= 6 m ohm) is confirmed for the 50mV transient response .

Forum Post: Regarding failures on LMD18245 Stepper Motor Driver

arun achoora — Wed, 27 Mar 2013 07:33:00 GMT

Hi All,

We have a design with LMD18245 Stepper Motor Driver .

Here we could notice -5V noise on the winding connections(OTU1 and OUT2 pins) .Recommended maximum negative voltage(due to the forward bias of body diode) is -1.5V.

Has anyone came across such a situation?

Please let me know.
