AF2039, NMOSFET
The AF2039 using the external NMOSFET.
It is a high efficiency boost converter with 600mV feedback voltage.
A switching frequency of 550KHz minimizes solution footprint by allowing the use of tiny low profile inductors and ceramic capacitors.
The current mode PWM/PFM design is internally compensated
