IPD’s SIP series of non-isolated converters deliver high efficiency and excellent
transient response in the industry standard SIP package. The SIP series has 12
models with output voltages from 1.2 to 3.3V, and up to 6A of output current. The SIE
model SIP has power OK and remote sense pins, for added flexibility and improved
point of load regulation. The SIP and SIE family are available for vertical or horizontal
mounting. The series features over 7 Million hours MTBF, and use 100% surface
mount construction for maximum reliability.
