Part Number: LMZ34002

Hi All,

Need some help on the part LMZ34002RKGT. For the datasheet configuration Figure 35 Vin = 12v, Vout=-5v, can anyone please let me know the voltages on the following pins ?

VADJ = ? , SS=? PH = ?

Hi Siddharth,

For the setting Vin = 12V, Vout = -5V like Figure 35:

Vadj (measured to GND reference) = 0.8Vref
PH (measured to GND reference) = 17V, The voltage difference between input voltage and output voltage (Vin - (-Vout)) will be what the high-side FET see.

Can you let me know what some of your concerns with these voltages are?

Regards,

Jimmy

thanks for the reply Jimmy, do you mean 0.8Vref or 0.8V ?

Hi Siddharth,

To clarify the voltage on Vadj pin should be 0.8V.
