› Comprehensive portfolio covering all bus voltages: sub 5 V, 5 V, 12 V, 24 V, and 48 V
› Offered in controller or SiP form (integrated MOSFET for single package solution)
› Speed + Efficiency
– PI2007 and PI2127 lead the industry in response times
– SiPs have the lowest RDS(ON) out there
– Competition:
› IR: 30% lower RDS than IR’s DirectFET and 30% faster
response (80 ns vs. 120 ns)
› Maxim and Intersil >200 ns response time; LTC at 500 ns
› Flexibility
– High Low configuration pair PI2007 + PI2003
– PI2001 and PI2121 enable paralleling (up to 10) for
higher current applications
› Compact Form Factor
– PI2127 SiP is 7 x 8 mm = 0.28 x 0.32 = 0.087 in2
