Remote Voltage Sensing
VOSEN+ and VOSEN- are used for remote sensing and connected directly to the load. The remote sense
differential amplifier with high speed, low input offset and low input bias current ensures accurate voltage sensing
and fast transient response.
Start-up Sequence
The IR3500 has a programmable soft-start function to limit the surge current during the converter start-up. A
capacitor connected between the SS/DEL and LGND pins controls soft start timing, over-current protection delay
and hiccup mode timing. A charge current of 52.5uA and discharge current of 4uA control the up slope and down
slope of the voltage at the SS/DEL pin respectively.
