Comparing N-Channel and P-Channel MOSFETs: Which is best for your application?
This article compares the n-channel and p-channel power MOSFETs, introduces the complete Littelfuse p-channel power MOSFETs portfolio, and explores target applications.

Each output can be set from 0.8V to 99% of VIN at output currents over 20A, with efficiencies as high as 96%, making it suitable for use in 12 or 24V automotive, heavy equipment, industrial control, robotics and telecomms applications.
The adjustable 5.0 to 10V gate drivers enable the use of logic- or standard-level MOSFETs to maximise efficiency. There is a selectable fixed frequency between 50 and 900kHz and it can be synchronised to an external clock from 75 to 850kHz. User selectable operation mode can be continuous, pulse-skipping and low ripple Burst Mode.
The two-phase operation reduces input filtering and capacitance requirements. The current mode architecture provides loop compensation, fast transient response, fixed frequency operation, line regulation and current sharing with paralleled phases for higher current. Output current sensing is achieved by measuring the voltage drop across the output inductor, or by using an optional sense resistor for high accuracy.
The LTC3892 with two power good signals, adjustable current limit and fixed 3.3 or 5V output voltage options is offfered in a 32-lead 5 x 5mm QFN package and the LTC3892-1 is avaiable in a 28-lead TSSOP. Extended and industrial grades, a high temperature automotive range and a military grade from -55 to 150°C.
