Part Number: LM2642 Hi Joseph,
I am targeting 10A nominal load, 40mV ripple, transient voltage excursions kept within 200mV for current excursions up to 10A. The application isn't sensitive to solution size, power density, or efficiency.
I am open…
Part Number: LM2642 I have read through the datasheet for this part and see typical application circuits for a 3V/5V single-phase/dual-channel application (Figure 2) and a dual-phase/single-channel 1.8V application (Figure 3). I was wondering if a 12V…

Dear sirs,
We have some strange situation with this device - LM2642. We've done our own design based upon the one presented in datasheet with some modifications based on nominal values calculation of inductors, capasitors and loop…
Part Number: LM2642 Hi,
On the case of Figure 2. Typical 2 Channel Application Circuit on Datasheet P.7, my customer thinks Q1 gate voltage which is from HDRV1 pin is as follows:
"Q1 gate voltage" = VIN + VDD - Diode VF(D3A).
Is his understanding…

Part Number: LM2642 Hello expert,
Customer would like to use LM2642 to implement below condition. For output 1, they will need to parallel high / low side MOSFET for higher output current of output 1. They are wondering if driver source(0.5A)/sink…
