No, MAX15158 does not have internal MOSFET driver. It requires an external MOSFET driver. We suggest to use the MAX15013 as indicated in this simplified block diagram of a single phase boost converter…
Yes, MAX15158 requires an 5.6V to 14V external power supply applied on its DRV pin for the internal circuits and reference to power up.
Take a look at the Soft-Start and Shutdown Sequence with EN/UVLO…
One MAX15158 device can support 1-phase or 2-phase. Two MAX15158 devices can be connected together to support 4-phase design. Here are some simplified circuits that show how the MAX15158 can be implemented…
For Boost topology, the minimum input voltage is 8V and there is no maximum limit for input voltage since that will be determined by the external fet seleted for the final design.
The OCP level can be set by the sense resisor and using a resistor connected to ILIM pin. Theoretically there is no hard limit on current capability of MAX15158. The current capability is determined by…
As stated in the data sheet under the Absolute Maximum ratings the MAX15158 can operate from -40ºC to +125ºC. The absolute maximum temperature rating of +150ºC is for Junction Temperature.
