MOSFET Selection to Minimize Losses in Low-Output-Voltage DC-DC Converters

FOM : Figure-of-Merit(성능지수)

A figure of merit is a quantity used to characterize the performance of a device, system or method, relative to its alternatives.

MOSFET 선택 요령

- 낮은 On 저항(low on-resistance)

- 좋은 성능지수(Low FOM, lower RDS(ON) x QGD)

- Low internal series gate resistance (RG or gate ESR)

- Low parasitic package inductance

- Low thermal resistance

- Robust Forward Biased Safe Operating Area(FBSOA)

- Unclamped Inductive Switching(UIS)

- 작은 것이 좋다(smaller Packaging Technologies)

  Chip-Scale Package(CSP)

  Ball Grid Array (BGA)

  EMI성능도 좋다

- 패키지형태도 중요하다(packaging technologies)
